fix(test-types): Loosen pydantic strictness on internal pydantic models

[fselmo]

🗒️ Description

Alternate solution to #1997.

Fix #1998 and #1999 by loosening restrictions on internal models. The goal of keeping some models strict and explicitly turning strictness off is so test writers have their code raise errors if they provide incorrect fields, not so we can be sticklers on internal models. This will only cause headaches I believe.
