Replace deprecated LLMChain with prompt | llm to follow LangChain's RunnableSequence API. Changes: - Remove deprecated LLMChain - Add prompt | llm - Update llm and prompt variable extraction - Kept full backward compatibility Reason: LLMChain was deprecated in LangChain 0.1.17 and will be removed in 1.0. This change prevents future breakage and removes warnings. Impact: No behavior change. Fully backward-compatible. Let me know if any adjustments are needed.
