You are right in terms of the wrong notes in her Liszt, although her Chopin is far from flawless either.
A lot of the stuff in the Liszt is just circus fanfare. If you sit down and work on it the proper way, then the technical challenges will be overcome. In her case, she had probably just not been working on the piece long enough (she says two months) and she even missed three pages out in her performance. She was clearly not ready to give a performance of the piece; it's very puzzling why her teacher did not dissuade her from playing it in the concert. From these videos, it seems the teacher is well-to-do, but unfortunately has set rather low standards for her students and might not even be going about things in the right way as the girl clearly has potential.
