This works the other way too. If you want to use an ally only power on a target, then that's your choice, not theirs. If they were your enemy, why would they refuse? So if they're your ally, it's even more of a reason to accept it.
I can think three words that say why they would refuse.
Dark. Pact. Warlock.
Your Glorious Sacrifice Warlock (Dark) Attack 1
Daily ✦ Arcane, Implement, Necrotic, Poison
Standard Action Ranged 10
Target: One creature
Effect: Before the attack, you can deal damage to an ally adjacent to you equal to your Charisma modifier. If you do so, you gain a +2 bonus to the attack roll.
Attack: Charisma vs. Fortitude
Hit: 3d8 + Charisma modifier damage. If you dealt damage to an ally as part of this power, the target takes ongoing poison damage equal to your Charisma modifier (save ends).
Dark Pact: The ongoing damage is instead equal to your Intelligence modifier + your Charisma modifier.
Miss: Half damage, and no ongoing damage.
Yeah, I don't see myself being allowed to deal 4 damage to that kobold as a 'cost' for dealing 8 ongoing damage to that dragon over yonder.z
Fortunately, the rules allow for that kobold to say he is unwilling to receive this power.
