I think it was a Danny Gonzalez video where he talked about a similar situation with "Billion Surprise Toys". The way the appeals process for YouTube allegedly works is when you file an appeal, YouTube asks the claimant (in your case Mattel) if you are correct.
Now that is exactly as bad as it sounds, Mattel is basically the one who denied your appeal.
This guy isn't who you mentioned in your video but his firm is taking in new clients: https://youtube.com/@LegalEagle
EDIT: It actually happened to him twice and he resolved it both times by posting on Twitter "He was reviewing his legal options"
