Description

By @qdrddr: I would recommend using the LiteLLLM Client (not to be confused with LiteLLM Proxy), which can work with a very large list of LLM Providers. @Remon128

This is LiteLLM Proxy implementation PR (Not the client you want in this PR), but could be used to extend the functionality to be used for other providers.
