This is a cool project on technical merits but by commercializing it, you're begging for a lawsuit. I nearly-recognize a couple of your logos, which could be a problem for you. As you've almost certainly used non-free sources in your training set, you'll be defenseless if somebody comes after you for trademark infringement.
And, as somebody who has made logos in the past? I'd feel pretty secure in the knowledge that your "AI-generated" works are not protected, and dissatisfied with rasterized versions with all their weird artifacts. It would take very little time for me to make a vectorized version of one of your logos that would look way better and you would have no legal recourse. My only real fear would be that I'd be ripping off somebody else's logo.
Isn't the usual workflow "pay me and I'll make a logo for you", not "here's a bunch of premade logos for sale"?
