feat: Update handling of tools_strict to ensure compatibility with vLLM

[Emil-io]

Proposed Changes:

Only add the "strict" dictionary to the openai_tools for generation, if tools_strict is available.

This ensures compatibility with vLLM (which adopts the OpenAI Interface). vLLM throws an error, if the "strict" dictionary is part of the tools list:

openai.BadRequestError: Error code: 400 - {'object': 'error', 'message': "[{'type': 'extra_forbidden', 'loc': ('body', 'tools', 0, 'function', 'strict'), 'msg': 'Extra inputs are not permitted', 'input': False}

How did you test it?
