Is your feature request related to a problem? Please describe.
When you inherit modelmetaclass, the dataclass_transform decorator gets lost, resulting in LSP not being able to source fields for schemas

Describe the solution you'd like

add @dataclass_transformer(kw_only_default=True, field_specifiers=(Field,)) to the new metaclass here:

Can either be sourced from pydantic or dataclasses. Field is the schema field.
