Nope. Formed as a part of the monsoon trof that was in the Caribbean. We've (I'm a meteorologist) been watching it for the better part of a week.

Is it possible this trof got a kick from the remnants of a front?

Nope. The low pressure started down in the extreme SE Gulf/NW Caribbean. But before that it was a trof in the Caribbean. The front didn’t reach that far. It finally closed off because of thunderstorms lowering the pressure (latent heat release of condensation in the convective complex). It’s of tropical origins.
