You say besides Kayle, but I think Kayle is one of the strongest for an AoE Support. Leona has a nice amount of AoE, yet not that much damage. Karma only has one AoE ability, but it's quite strong in lane even before items. Annie's probably S-Tier, and may be better than Kayle in some situations. Taric has AoE spells as well as some strong buffs/debuffs on said spells.

Oh, hold on, did you want supports with strong AoE, or supports that are strong against it?

if you're talking about against an AoE comp, Janna's innate movespeed helps a lot with dodging the damage, Taric's efficient duo heal can mitigate a good chunk of the damage, Maokai's ult can really mess up an AoE comp, Lux's shield can absorb damage for both players, etc.

Against AoE, you really have two choices. Pick someone who can help your side avoid it, or pick someone who can help your side ignore it.
