OLLAMA_API_BASE not taking effect when running without Docker serve, but in a container

[jonathanortega2023]

Might be related to #987 I think this issue is still persisting for non-docker serving users running in a container. I have R2R setting up in a python3.12-slim image and OLLAMA_API_BASE set in env but still could not access external Ollama.

Please ensure Ollama is running externally if you've excluded it from Docker and plan on running Local LLMs.
Do you want to continue without confirming an `Ollama` connection? [y/N]:
