If you don't know 100 living pianists, then maybe you are excused 
EDIT: MY list would also include some Asian pianists, I just have trouble in general remembering people's names...
My list has 100. I think the proficiency of all of them seems to perform better (or their position in the world of piano teaching or music) is more important than LL's.
But note: It contains 2 or three
teachers as well, who didn't (or: rarely) perform(ed) in public, so there aren't (or: there don't seem to be) recordings of them. Some of them only stem from my own circle of acquaintances, and,, as I must repeat: It's only SUBJECTIVE and PERSONAL opinion of mine.
Nevertheless, let's go...:

37 Cecile Licad,
38 Philip Martin,
39 Antonio Iturrioz (whose "El Cocoye" on YT is mindblasting, imho !! Note: He was very ill, for a time, losing control of one of his hands! But then, luckily, it seems to have become better, again!! ),
40 Brunhilde "Bruni" Herbel (who was student of Cortot and friend and classmate (in normal school, when she was young) to my mother ), but I don't think you know about her.

49 Idil Biret,
50 Fazil Say (maybe, but I'm not too convinced.),
51 Alfred Brendel ( I don't like his playing and stage-presence too much, but he's famous!),
52 Abdel Rahman El Bacha,

1 ) Christoph Eschenbach,

61 Homero Francesch,
62 Andrei Gavrilov,
63 Andreas Groethuysen ( and his duo-partner Yaara Tal),
64 Angela Hewitt,
65 Leslie Howard (of whom I have a super recording of "Sophie Menter's" "Ungarische Zigeunerweisen", i got it as a present. ),
66 Cyprien Katsaris ( though he was struck by an illness, which I was very sad about, I dislike his arrangement of Gottschalk's "Banjo", but I like his recordings of some of Amedee Mereaux' (very hard) "Etudes" very much, which are on YT! ),
67 Freddy Kempff (with 2 f? maybe. He can be found on YT as well! Check him out!),
68 Evgenyi Kissin ( I don't like his playing too much, but I think it's better than LL's ),
69 Radu Lupu ( unforgettable with the cigar in Beethoven's alla Turca, imho),
70 Olli Mustonen ( I like his name! ),
71 Garrick Ohlsson,
72 Dieter Goldmann (I'm not sure whether he's alive or not, but I've got 2 Chopin-Concert-recordings of his on CD - very nice! ),
73 Alfredo Perl,
74 Maria Joao Pires (who quickly replaced one Mozart-Concert with another, since orch had practised the "wrong" one),
75 Gabriela Montero, who is Venezuelan born, like Teresa Carreno was,
76 Mikhail Pletnev,
77 Tzvi Erez (who, on YT, shows a , imho, very nice performing of the "military" polonaise of Chopin!),
78 Pascal Roge ( who, recently, was topic of a competition-quarrel, but that would be to discuss on another place, I think),
79 Olga Scheps,
80 Dimitris Sgouros (I heard him on TV many years ago, playing Chopin Ballade g-minor. Some attack him, because of the lack of musical depth, but I think he would outmaneuvre LL. ),
81 Norman Shetler,
82 Grigory Sokolov (I don't like some of his moves, but for LL his playing would be sufficient, I think. ),
83 Martin Stadtfeld,
84 Mitsuko Uchida,
85 Arie Vardi,
86 Tamas Vasary,
87 Andre Watts ( of course!!! I experienced him years ago with the SaintSaens 2nd concert on TV...but watch out for his Liszt b-minor-sonata on YT, too! ),
88 Arcadi Volodos (maybe),
89 Elisso Virsaladze,
90 Anatol Ugorski (check out his mindblasting Chopin-Fugue a-minor on YT!! I love that sooo much!! ),
91 Emanuel Ax,
92 Robert DeGaetano,
93 Tobias Göbel, who was a pupil of Kämmerling, in the city I - near- come from. Thus, maybe not known to all of us. He bacame a teacher, but when once I heard him live in a concert hall, he didn't manage the Ocean Etude as encore too well, but he succeeded in the Grieg a minor concerto. He's good, I think.
94 Cory Hall (BachScholar), on YT. Though some might not like his playing very much, as I could see.
,
95 Jonathan Plowright (check out the "banjo" on yt!) ,
96 "Yuya" Wang,
97 Y. Avdeeva (Chopin-Competition-winner. Not really my taste, but she did it. Did LL ? ),
98 Peter Rösel (comes from the former DDR (GDR)). I dislike him, because on German TV he once upon a time he discouraged amateurs very much OFF the Waldstein-sonata (which, unfortunately, I was learning just at that time.) I "kicked" his words, successfully.. But, nevertheless, he should be at least as good as LL. ,
99 Tobias Sing "pianovirus",
( Epanalepsen-Dieb!
)
100 A. Riegler (look, styleblossom / style)
I haven't forgotten you!
Very cordially, 8_octaves!
