Support top level `List[T]` type for iterable's, partial's and raw responses

[aretrace]

It would be really useful to be able to return an object type of list when using client.chat.completions.create_iterable / create_partial / create_with_completion. The patched client currently only supports list with vanilla create:

class T(BaseModel):
        ...

response = client.chat.completions.create(
        model="gpt-3.5-turbo",
        messages=[
            {"role": "system", "content": "..."},
            {"role": "user", "content": "..."},
        ],
        response_model=List[T],
    )

create_with_completion would be a priority for this support (create already works).

Agree, the design of create_iterable is a bit odd and clashes with create_with_completion.
Imho the cleanest implementation for users would be to just allow to pass a list[BaseModel] / List[BaseModel] for responsemodel as suggested.
