This has been going on for quite awhile. Those Youtube channels are usually just broadcasting an unlicensed stream of Fox (and others). Then a little box will appear (usually asian or india themed).
It is an attempt to circumvent/confuse the AI copyright checks and fair-use exceptions to the Youtube policies. (normally these are livestreams and deleted upon completion).
The chinese knitting lady has been around since at least 2021 or so. When a channel gets closed down, it will reappear under a different one. (three strikes per channel so just rides out the strikes and starts another). It's not really one person. It is a bunch of people and they just use the knitting video they downloaded from somewhere.
Another popular one that used to circulate had a couple of cats in the streamer's box window.
