Further reading in the Ai disclosure community forum suggests that the way you are describing having used generative Ai to assist in your coding does not fall under what the tag is meant to imply. I don’t know how to link exactly to it via my phone, but the comment thread from about a year ago between Nikkoan Games and Leafo is what I’m referring to. I can try to send you a link to it directly when I am home later.
Viewing post in AI Involvement With Code comments
I don't know how to link to a specific post in the thread, but this user only has a few posts so you can find it that way pretty easily.

Some other reading on the same thread has me believing that the intent was that the tag applies to assets, not games. Games are not required to use the tag (which... is confusing as the tag is present, and a choice is required when making a game page...) and that generative AI use in developing code (far beyond the scope of what you described having used it for) is not what the tag is intended for. I think you could turn your project listing back to no AI and remain well within the intent of the admins.
