How to ensure my AI characters follow age standards?

I operate an AI character chat platform where users interact with AI-generated characters through text, images, and video. The platform serves a general audience (13+) with certain content categories restricted to verified 18+ users only.

For the 18+ content categories, I'm looking for an attorney who can help me with 1) compliance with laws around AI-generated content, and 2) standards to ensure all characters are clearly perceived as adults, not minors.

What type of attorney should I be looking for, and does anyone have specific recommendations?
