I would allow it, if the rogue in question has the rapier. He's threatening the Troll, he can make a melee attack or an attack of opportunity. Even if he doesn't attack, he's still threatening.
If the fighter on the other side stopped attacking for a round to, say, drink a potion; would you let the troll walk away without an attack of opportunity because he was no longer threatened? No, of course not. It's obvious that the Troll is still threatened, even if the fighter doesn't attack.
The same thing goes to the rogue. The troll is threatened by the rogue's rapier, regardless of whether the rogue attacks with it or not.
Now that we know the Troll is being threatened by two people on opposite sides, we know that the Troll is flanked.
Now, you can make a sneak attack against a creature if it is flat footed (the Troll is not) or flanked (the Troll is).
Ok, the Troll is flanked, and can be sneak attacked.
You can sneak attack with a spell, and you can sneak attack with ranged weapons if you are within 30'. The Rogue is within 30'.
End result - The rogue can sneak attack the Troll with his wand, as long as the Rogue also has some way of threatening the Troll (for example, a rapier).
