葛尧 e780433f6b Fix token_usage None issue in ChatOpenAI with local Chatglm2-6B (#14493) ... When using local Chatglm2-6B by changing OPENAI_BASE_URL to localhost, the token_usage in ChatOpenAI becomes None. This leads to an AttributeError when trying to access token_usage.items(). This commit adds a check to ensure token_usage is not None before accessing its items. This change prevents the AttributeError and allows ChatOpenAI to work seamlessly with a local Chatglm2-6B model, aligning with the way it operates with the OpenAI API. <!-- Thank you for contributing to LangChain!
