LlamaIndex RAG Pipeline and DSPy Optimization

Implement an advanced RAG pipeline using LlamaIndex to retrieve relevant Alaska probate laws and precedents. Describe how you'll chunk documents, choose an embedding model, set up the vector store, and how the retrieval mechanism will feed into the Claude Opus 4.1 agent. Further, explain how DSPy will be used to programmatically optimize prompts and few-shot examples for improved legal accuracy and reduced hallucinations.
