Describe the bug
I'll illustrate an example of expected behaviour using a pydantic.BaseModel:

class SomeType(BaseModel):
    some_attr: Annotated[str, Field(min_length=2)]

@post("/")
def endpoint(data: SomeType) -> SomeType:
    return data


app = Litestar([endpoint], debug=True)

Then I curl* an invalid input and a pydantic_core._pydantic_core.ValidationError is raised.

But if I change the SomeType to this:

@dataclass(config=ConfigDict(validate_assignment=True))
class SomeType:
    some_attr: Annotated[str, Field(min_length=2)]

There is no error raised, even with the same invalid input curl*

*curl command:

curl -X 'POST' \
  'http://127.0.0.1:8000/' \
  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -d '{
  "some_attr": "s"
}'
