What's the difference between humans and LLMs? The difference is that the creators of laws are humans, and the purpose of laws is for humans. Authors write books with the expectation that they will be read by humans, and copyright law was written with unstated assumptions, like the fact that books have an effect on a person's mind after reading it.
IMO the spirit of the law would prohibit LLMs from training, and the letter of the law leaves room for that only because nobody thought to write down "books are for people to read".
Laws are not only for humans, there are laws for bots as well, like anti spam, but that's besides the point because in reality behind LLMs there are humans and so humans still control them, therefore laws target them too, and now it looks like humans using LLMs to train via ingestion of books is deemed fair use.
I agree that laws don't only apply to humans, but they are only for humans. The legal system is for our benefit.

Which is orthogonal to my point.
