fix: resolve SyntaxError and improve code structure in autoagents.py

- Fixed incorrect indentation causing SyntaxError on line 436
- Removed duplicate llm_instance creation and OpenAI detection logic
- Cleaned up nested try-except blocks for better readability
- Preserved backward compatibility with OpenAI structured outputs
- Maintained all error handling and retry mechanisms
- Fixed logic flow to properly check for OpenAI support once per retry

This minimal fix addresses the critical syntax issues while maintaining
all existing functionality.
