Add ChatLiteLLM Tutorial

[ishaan-jaff]

Hi I'm the maintainer of liteLLM https://github.com/BerriAI/litellm/

liteLLM adds support for 50+ models

ChatLiteLLM() is integrated into langchain and allows you to call all models using the ChatOpenAI I/O interface
https://python.langchain.com/docs/integrations/chat/litellm

Here's an example of how to use ChatLiteLLM()

ChatLiteLLM(model="gpt-3.5-turbo")
ChatLiteLLM(model="claude-2", temperature=0.3)
ChatLiteLLM(model="command-nightly")
ChatLiteLLM(model="replicate/llama-2-70b-chat:2c1608e18606fad2812020dc541930f2d0495ce32eee50074220b87300bc16e1")
