Add Ollama Support to RetoolAI

Thanks for all the work on RetoolAI. It would be great if you could add Ollama support to RetoolAI. It would allow testing of open source factorized LLMs.

Hey @nsteblay, thanks for the request. I've logged this internally, and can update this post as we hear any additional information!

As Ollama now supposedly supports an OpenAI-style API, could you not just expose the configuration for OpenAI so we can point to an Ollama instance instead?
