The specific name "Toxirat" does not correspond to a recognized, formally named location within Final Fantasy VII Rebirth.
It's possible you might be thinking of an enemy with a similar-sounding name, or perhaps a location with a distinct "toxic" theme. The most prominent area fitting such a description is the Toxic Dump.
