Add LiteLLM Connector to LangFlow

[flefevre]

Hello,

I would like to suggest adding a connector for LiteLLM to LangFlow. LiteLLM is a lightweight and fast open-source library for integrating various LLM providers with a simplified interface. Including this connector in LangFlow would offer several benefits:

1. Broader compatibility: Support for multiple LLM providers through LiteLLM's unified interface.
2. Improved usability: Simplifies the process of integrating and switching between LLMs.
3. Community adoption: LiteLLM has an active and growing user base, making it a valuable addition to LangFlow.

Proposed Solution:

• Create a new connector module in LangFlow that interfaces with LiteLLM.
• Ensure compatibility with key LiteLLM features, such as provider switching and request optimization.
• Provide documentation and examples for users to set up and use the LiteLLM connector.

This feature would make LangFlow more versatile and appealing to users seeking streamlined LLM integrations.

Thank you for considering this enhancement!

Best regards,
Francois
