Photography / Image Rights: AI art used without permission

I'm in a difficult situation and trying to figure out my next steps.

AI art used without permission. I've been dealing with this for about 6 weeks now and the situation isn't improving.

This involves original creative work over the past 19 months. I do have documentation proving my ownership and timeline.

Should I hire a lawyer for this or try to handle it myself?

Been there. Here's what I learned.

In my case, it took about 3-6 months to resolve. The key was having everything documented.
