I think that's called a school
If you think going to school to get an education is the same thing as training an LLM then you are just so misguided. Normal people read books to gain an understanding of a concept, but do not retain the text verbatim in memory in perpetuity. This is not what training an LLM does.
The output is what matters. If what the LLM creates isn’t transformative, or public domain, it’s infringement. The training doesn’t produce a work in itself.
Besides that, how much original creative work do you really believe is out there? Pretty much all art (and a lot of science) is based on prior work. There are true breakthroughs, of course, but they’re few and far between.
