That's a pretty reductionist view. Even maximally pro-IP laws usually have significant carve-outs for derivative works or other scenarios; see for example the US's extensive "fair use" doctrine.
You're begging the question: it's not established the LLM models are derivative or fair use under those laws.
Also, the de facto state of fair use in the US is not what I would call "extensive".
Do I have to repeat "copyright violation isn't theft" on every post for eternity?
If I make copies of Project Hail Mary and sell them at half price, do you think it's obvious that should be legal? I think Andy Weir would have a decent moral as well as legal case for theft.
