Path Not Connected Issue

I started seeing this randomly whenever I try to use any response AI block. I copied my vf file and tried it on a different account and it works on another account. Is there some limit I hit and I can't use the ai model anymore on that account?

I figured out I did exceed my 100k free tier limit while I was setting things up and testing. Does anyone have an idea of how many tokens you might use in a typical month for a website with 30-50k monthly users? It's hard to imagine how much use my bot would get, obviously I can limit use per user.
