Any open source libraries that can help me easily switch between LLMs while building LLM applications? [D]

I have been building open source tools which would be using LLMs and RAG, however, there is a plethora of LLM models and frameworks to choose between, including OpenAI, Huggingface, AzureOpenAI etc. Writing a new class and extensions for each of them can be difficult. I was curious if there was more easier way like a tool/framework which unifies maximum number of LLM apis under one umbrella so that I don't have to write a new class for everything?
