Description

• Updated various components to support handling multiple function schemas instead of a single schema.
• Enhanced the OpenAI LLM integration to handle multiple function schemas, including adjustments in input validation and response handling.
• Refactored utility functions to support the generation of schemas for multiple items and added new tests for these changes.
• Updated documentation and example notebooks to align with the new handling of multiple function schemas.
