Absolutely not. AI images can be mass-produced and two people using the same seed will be able to create the same image. If they're copyrightable nothing would be stopping a company from making millions of images a day and copyright trolling anyone who tries to use them.
There's also a lot of other issues like image AIs being trained on real copyrighted data, so nothing stops me from saying "Hey, generate an image of Kirby". It's hard to argue that you own that image when it clearly depicts something that isn't yours.
