Magneto *does* fight telekinesis with regularity. Magneto's not even high-end for some of the characters anyway...
Heck, let's go with someone who's not top-tier, but would be super hard for Jedi to deal with. Photon Monica Rambeau. She turns into energy. She blasts harder than any jedi or sith has ever stopped with force-absorb. She can absorb lightning coming at her. She's way too fast to be hit by force storm, death field, or the like. Strong will and, like most avengers, some anti-telepathy training.
DARTH POWER
If we are talking about Jedi like Anakin and Obi-Wan, I'd say they take all the street levelers like Spider-Man, Captain America and Wolverine.
Spider-man's actually rather significantly super. He's got spidey-sense which is a least equal to Jedi precog, he's got crazy-fast movement, agility, and reflexes, and his webs are very hard to deal with. And he can benchpress a buss.
Spider-man would be a difficult foe even for rather strong Jedi. Not unbeatable, but quite hard.
