Meggan took him out rather easily. If she was written that way, the Titans wouldn't have a hard time with their opponents. Also, she held her own against Wyld a creature created by Raven and read Bombshell's mind all the way from Australia.
To be honest Mammoth is mentally underdeveloped and would be easily confused by such a tactic. It would not be sufficient to defeat Thor as he can will Mjolnir to hit the "true" targets instead of illusions. I've never seen her use TP in the more unpleasant ways I listed above: mind control, screwing with motor functions, attacks on the psychic plane.
Reading Bombshell's mind was not a willing choice. Her personal code dictates that using TP to read friends' minds is wrong; she had to be persuaded to do it.
