"Korosensei" probably wasn't her idea, anyway. "Sensei" is merely a suffix and, thus, shouldn't be counted for the translation. His name is written with the Kanji for "to kill", according to Rikai-kun. Thus, his name "Koro" probably really is only an abbrevation of "Koroshiya". And even if you factor in the "Sensei", how does one come to "unkillable teacher"? That would rather result in "Kill the teacher", "teacher to kill" or something similiar.

I don't know if "Unkillable teacher" is the official translation according to the author, but if it isn't, it being an abbreviaton of "Koroshiya" might be the better assumption.
