In the marginalization of psionics in 2e, essentially all demons and devils lost their psionic powers. In 1st edition most that has spells also had psionics.
According to The Complete Psionics Handbook, for AD&D 2E, the following fiends had psionic powers: Baatezu (amnizu, cornugon, gelugon, and pit fiend; powers of control and cruelty, effective psionicist level of HD-1), Morti (I have no idea what these are, myself, just that they're some outer-planar denizen, but the one-line entry looks pretty insane; I assume Morti was/were a godlike creature/race, or something, judging from the power score of 20,500, 20th-level psionicist equivalent for using powers, and possession of all psionic powers...), Tanar'ri (babau, succubus, nalfeshnee, marilith, balor, glabrezu, and hezrou; powers of fire control, torture, and shape changing, effective psionicist level of HD-3), and Yugoloths (only arcanaloths; powers of travel and combat; effective psionicist level of 13).
So you could reasonably assume that these creatures also have psionics in 3E, if you felt like it, and assign them the Psionic template (or is it the Phrenic template? Or just an effective psion or psychic warrior level for purposes of powers known, power points, and manifester level).
