"Butlerian jihad" comes from a science fiction novel from 1965 (Dune, by Frank Herbert). They didn't know about current political correctness 60 years ago.
The comparable word is "crusade". If it's OK to use the word crusade, it's OK to use the word jihad.
(My opinion is that neither should be used, but a majority of Americans disagree with me).
To be pedantic, crusade means "holy war" and jihad means "to struggle", so jihad should be more acceptable than crusade, but in English, jihad essentially only has the holy war meaning.
