I'm going to play the devil's advocate and tell you that AI is a creator in the same way as a human being, that it exhibits creativity and that it draws inspiration from all kinds of sources.
No artist works in a vacuum. Someone who writes a book has definitely read a lot of novels, 1,000, 2,000 or even 10,000, every one of which has been a source of inspiration. However, if an artist publishes a book, the use of the books that he or she has read for inspiration will not be considered unauthorized. So it's hard to understand why it would be different for a machine that, ultimately, is also a creator.
