Can someone tell me if there's an episode where telepaths (in Starfuries) fight Shadows?
Telepaths do fight Shadows, but never in Starfuries.
In "Ship of Tears" Besters presence on the WhiteStar scares off a ShadowShip, but he does no fighting (the WS shoots down a few ShadowFighters, but without teepy help).
In "Walkabout" Lyta is the first telepath in B5-era history to attempt (and succeed - barely; as she hasn't yet accessed her enhanced powers at that point) jam a ShadowShip from a WhiteStar, and three Minbari teeps jam three more ShadowShips from a Sharlin.
And in "Shadow Dancing" we see Minbari teeps jamming ShadowShips from the relative safety of their Sharlin again (and how that safety is not so relative when dealing with Shadow Slicer Beams).
I suppose that in the big battle seen in "Into the Fire" there were also teeps jamming ShadowShips, but we don't see them.
After that time there are no more ShadowShips around to jam.
And thought logically, if you had teeps that could jam shadows, you'd be stupid to put 'em in Starfuries where even a lowly ShadowFighter could take them out of the fight with one blast from it's Polarity Cannon; you'd put them on your biggest and best defended ships - even if those defenses can't hold off a true ShadowShip, it will at least keep your teeps relatively safe from all the smaller ShadowVessels.
Now... following AoG rules it would be possible to do a fight of a Black Omega starfury flight, every fighter with a telepath as pilot against a group of ShadowVessels. And I suppose if they were to jam their opponents, they might even be quite effective - as long as they can kill the enemy before they can no longer jam them (then it becomes a simple "ShadowFighters against Starfuries", with predictable results barring too good luck with the dice).
But in the big picture it would be a stupid idea, since in most fleets you have a rather limited number of telepaths (like, one teep per 5 big ships or so) - and it'd be dumb to put them in fighters where they could be killed soo easily.
