> Training an LLM is akin to human learning. It is legal to read a textbook about music to learn music

If you learn a little too hard though, and reproduce the original textbook in it's entirety, you'll get in trouble.

My guess is that courts will determine that the training itself will not be found illegal, but either the AI companies, or the users, will be found liable for reproducing copywrighted work in output, and no one will want to hold liability for that.
