Issue:
[Bug]: Ollama cannot be added in the UI BASE_URL is missing
### What happened?

Ollama cannot be added in the UI BASE_URL is missing.

I want to use LiteLLM to host a number of devices with varying providers. One Ollama, another LM Studio, etc and expose it via the LiteLLM Proxy so I don't need to expose everything but can proxy everything through one portal.

### What LiteLLM version are you on ?

### Twitter / LinkedIn details

Hints from issue comments:
@devbysb: Hi by default it is localhost but I need to custom api_base the only way I've found is to use the config.yaml files. Is it possible to add this custom parameter on the ui ?
