I think you're repeating something that feels emotionally valid but in my experience, isn't factually (or legally) accurate.
I have found AI models to be frustratingly _obedient_ of copyright.
I'll be in a situation where I ask a specific question about what a document says, and the AI repeatedly says the work is copyrighted and it can't just tell me what it says _verbatim_, but it can answer specific questions for me in its own words (while telling me to check the original).
Two examples from my life are procedural questions about what Roberts Rules of Order would require in a given situation, and, what ASD STE-100 says about how to name/word things.
The applicable US law would appear to be USC 17 Sec 106 and 107, which on one hand limits derivative works, but on the other, allows fair use for purposes of teaching, scholarship, or research.
(USC references provided by AI, btw. Which I haven't read)
