I thought the Kaon tools might do it but I see not obviously.

The former is fairly trivial, esp. if you don't care about staying in the 2 variable fragment and you aren't trying to encode annotations and the like. A visitor on the OWL API ontology object would be easy. A few dozen lines of prolog against Thea. Not a large XSLT. The only question is you output formate. KAON2 translates to FOL clauses internally, I believe.

The latter probably requires a bit of thought as the axiomization isn't standardized. Though there might be something related to:
