Ref: Large project with PydanticAI?

I'm dealing with a fairly large project that revolves around integrating AI features in a SaaS.

So far we've been POCing with langgraph but I'm thinking of changing framework. Mostly motivated by the fact that langgraph is awful.

Since every one on the team are fans of Pydantic I'm considering PydanticAI/graph (no other valid reason so far, expect the documentation which is already amazing).

We're interested in fully agentic workflow, mutilple-agents graphs, various tools, with the possibility of forking graph based on human feedback. I know Pydantic does that but is there any large open source project that I could check out and present to the team ?

We're also logging everything with langfuse. It took effort in deploying it and I wonder if it would still work if we switched to Pydantic (but I'm guessing thats more of a langfuse question).
