Why custom model is restricted to Ollama only?

[privacyadmin]

Self hosted version supports only Ollama.

vLLM is also OpenAPI compatible but it seems hardcoded to accept only ollama/llama2 as the only option when loading available models.

Suggestion: Please consider removing the hardcoded Ollama only option for custom provider.

Thank you
