Bug Report

Hey, was playing around with the new gemini 3 flash preview model doing some OCR and when looking at the llm obs I noticed that ImagePart and FilePart types are not supported. As a result you get a kinda confusing UI where it looks like the LLM did not receive the right info:

This line comes from

dd-trace-py/ddtrace/llmobs/_integrations/google_utils.py

Line 239 in 9ac98cb

return Message(content="Unsupported file type: {}".format(type(part)), role=role)

  return Message(content="Unsupported file type: {}".format(type(part)), role=role)

Image Parts store their data in the inline_data attribute (containing bytes and mime_type)

Reproduction Code

Use google-genai python package and send an request with an imagepart in it.
