[Improvement] - URL for Judge LLM

# Is your feature request related to a problem? Please describe.
It would be nice if we could change the address of our Judge LLM, for example instead of OpenAI we may use APIM / Azure OpenAI.
I wanted to use the tool, but I can't because I only have Azure OpenAI :)

# Describe the solution you'd like
Perhaps some sort of OPENAI_URL env var
