opentelemetry-instrumentation-openai-v2: crash with `with_raw_response`: 'LegacyAPIResponse' object has no attribute 'model'

[beforeeight]

Describe your environment

Package version: 2.2b0

What happened?

File: patch.py
Line: 397
set_span_attribute(
span, GenAIAttributes.GEN_AI_RESPONSE_MODEL, result.model
)

should add " if getattr(result, "model", None) " , cause sometime result has no attribute "model"

Steps to Reproduce

    client = openai.OpenAI()

    messages = [
        {
            "role": "user",
            "content": TEST_CHAT_INPUT,
        }
    ]

    raw_response = client.chat.completions.with_raw_response.create(model=TEST_CHAT_MODEL, messages=messages)
    chat_completion = raw_response.parse()
    assert chat_completion.choices[0].message.content

and stream

    client = openai.OpenAI()

    messages = [
        {
            "role": "user",
            "content": TEST_CHAT_INPUT,
        }
    ]

    raw_response = client.chat.completions.with_raw_response.create(
        model=TEST_CHAT_MODEL, messages=messages, stream=True
    )

    # Explicit parse of the raw response
    chat_completion = raw_response.parse()

    chunks = [chunk.choices[0].delta.content or "" for chunk in chat_completion if chunk.choices]
    assert "".join(chunks)

Expected Result

no crash

Actual Result

exception raised

Is this from a call with with_raw_response or something else? Anyway please fill the steps to reproduce block with some code to reproduce the issue.

[beforeeight]

yes, that from with_raw_response,
from langchain_openai(version: 0.3.35):

  chat_models/base.py    line: 1208
line: 1208     raw_response = self.client.with_raw_response.create(**payload)

here is the code:

                return _construct_lc_result_from_responses_api(
                    response,
                    schema=original_schema_obj,
                    metadata=generation_info,
                    output_version=self.output_version,
                )
            else:
                raw_response = self.client.with_raw_response.create(**payload)
                response = raw_response.parse()
        except Exception as e:
            if raw_response is not None and hasattr(raw_response, "http_response"):
                e.response = raw_response.http_response  # type: ignore[attr-defined]
            raise e

Added a couple of reproducers if anyone wants to tackle this.
