I wouldn't say any of them tetras are deep bodied enough for and adult severum black phantoms just have tall fins I've seen 3-4cm black phantoms and serpaes picked off by 10cm angels and 12 cm red head geophagus the tetras I would say are 99% safe with angels and Severums arelemon tetra are a high body tetra, and should be fine. the ones at risk are short bodies like neon, cardinal, ect. rummy nose tetra are a short body, but they also get 2" so unless there is an adult sev or angel, they should be fine, and if they grow up with those fish, and you dont feed feeder fish they should never bother them. you could always have an ******* of a cichlid, so YMMV.
in any case, high bodied tetra, serpe, phantom, lemon, ect, should be fine.
