LlamaIndex OpenAI Pydantic Program

The `llama-index-program-openai` library is an integration for LlamaIndex that facilitates the generation of structured data using OpenAI's API in conjunction with Pydantic objects. It allows users to define explicit output schemas using Pydantic models, enabling robust and type-safe data extraction from LLM responses. Currently at version 0.3.2, this package follows the rapid release and modular development cadence of the broader LlamaIndex ecosystem.
