The LLM is not repeating the same book. The owner of the LLM has the exact same rights to do with what his LLM is reading, as you have to do with what ever YOU are reading.
As long as it is not a verbatim recitation, it is completely okay.
According to story telling theory: there are only roughly 15 different story types anyway.

Sort of.
If you violated laws in obtaining the book (eg stole or downloaded it without permission) it’s illegal and you’ve already violated the law, no matter what you do after that.
If you obtain the book legally you can do whatever you want with that book, by the first sale doctrine. If you want to redistribute the book, you need the proper license. You don’t need any licensing to create a derivative work. That work has to be “sufficiently transformed” in order to pass.
