Nowhere does it say Sneak Attack requires an attack roll, so people insisting it does need to cite something if they want me to buy that.
Now, can Precision Damage be applied to an AoE spell? That is a separate question. RAW is a little murky since it doesn't say outright, but the language "must be able to pick out a weakspot to attack" seems to mean RAI the answer is No.

The level 10 Arcane Trickster feature Surprise Spells allows you to deal sneak attack damage with ANY spell that deals damage. With the associated FAQ specifically calling out Fireball and Magic Missle. AoE and Single Target spells that don't make attack rolls.
Since there are specific call-outs to Melee and Ranged touch attack spells adding sneak attack damage and a precedent for AoE and Single Target non-attack roll spells requiring Surprise Spells to deal sneak attack damage that only Spells that make attack rolls qualify for sneak attack damage.
