chore(replay): improve replay robustness with un-validated construction (#3414)

Browse source 
# What does this PR do?

some providers do not produce spec compliant outputs. when this happens
the replay infra will fail to construct the proper types and will return
a dict to the client. the client likely does not expect a dict.

this was discovered with tgi, which returns finish_reason="" when valid
values are "stop", "length" or "content_filter"

## Test Plan
