### Describe the problem

When using the DSPy package to interact with OpenAI, along with MLflow's OpenAI flavor, MLflow tracing fails to properly parse the content of the response objects. This issue makes it difficult to fully track or log the API responses, which can affect model output tracking and result analysis. I am seeking a solution to ensure that MLflow tracing can correctly parse and record the response object content, allowing the OpenAI flavor to function as expected.

During my experiments, the returned result appears to be a Python Response object like the image below.

Here is the expected result for the Response field that I found in the official documentation:

### Code to reproduce issue

<!-- PLEASE KEEP BACKTICKS AND CHECK PREVIEW -->
# Load data
```Python
import random
from typing import Literal
from dspy.datasets import DataLoader
from datasets import load_dataset

# Load the Banking77 dataset and save to ./data.
CLASSES = load_dataset("PolyAI/banking77", split="train", trust_remote_code=True, cache_dir="/Volumes/ai_default/stockllm/sample").features['label'].names
kwargs = dict(fields=("text", "label"), input_keys=("text",), split="train", trust_remote_code=True, cache_dir="/Volumes/ai_default/stockllm/sample")
# Load the first 2000 examples from the dataset, and assign a hint to each *training* example.
trainset = [
    dspy.Example(x, hint=CLASSES[x.label], label=CLASSES[x.label]).with_inputs("text", "hint")
    for x in DataLoader().from_huggingface(dataset_name="PolyAI/banking77", **kwargs)[:2000]
]
random.Random(0).shuffle(trainset)
```
# Inference
```Python
import mlflow

mlflow.start_run()
mlflow.openai.autolog()
import dspy

dspy.settings.experimental = True
dspy.configure(lm=dspy.LM('gpt-4o-mini-2024-07-18', api_key=openai_api_key))

# Define the DSPy module for classification. It will use the hint at training time, if available.
signature = dspy.Signature("text -> label").with_updated_fields('label', type_=Literal[tuple(CLASSES)])
classify = dspy.ChainOfThoughtWithHint(signature)
classify(text="<Some questions ...>")
