Fixes #3702 When using langchain-google-genai with CrewAI, the model name would include a 'models/' prefix (e.g., 'models/gemini/gemini-pro') which is added by Google's API internally. However, LiteLLM does not recognize this format, causing a 'LLM Provider NOT provided' error. This fix strips the 'models/' prefix from model names when extracting them from langchain model objects, ensuring compatibility with LiteLLM while maintaining backward compatibility with models that don't have this prefix. Changes: - Modified create_llm() in llm_utils.py to strip 'models/' prefix - Added comprehensive tests covering various scenarios: - Model with 'models/' prefix in model attribute - Model with 'models/' prefix in model_name attribute - Model without prefix (no change) - Case-sensitive prefix handling (only lowercase 'models/' is stripped) Co-Authored-By: João <joao@crewai.com>
