Yes, provided you can separate the two (e.g. a book and illustrations in one case). AFAIK the courts have still not ruled on what happens when AI and human contributions cannot be separated etc.
It varies a lot in other countries, but in most (if not all) an AI cannot hold a copyright.
AI isn't a legal entity that can do anything, let alone hold a copyright. It is an inanimate box of numbers.
The only two things that can transact with any legal system in any way are humans and groups of humans.
