Valid, but for all the crap that LangChain gets it at least has its own layer for upstream LLM provider calls, which means it isn't affected by this supply chain compromise (unless you're using the optional langchain-litellm package). DSPy uses LiteLLM as its primary way to call OpenAI, etc. and CrewAI imports it, too, but I believe it prefers the vendor libraries directly before it falls back to LiteLLM.
