If they can find anyone. Similarly to there being no mark of an enchantment, I didn't particularly notice a maker's mark. Whether or not anyone--kids, parents, teachers--remembered who gave them the dolls. Wasn't there reports of dolls vanishing from shops?

Lucifer hears a lot of rumor on any given day. Most of it gets filtered out and ignored. But some of it shakes between the cracked flows of his mind to be shaken out later. He cared less about the dolls, obviously, but disappearing stuck. Disappeared, not stolen.

Better yet... He's still playing, if only because it keeps him from having to answer a renewed barrage of inane questions from the children, walking backwards in the direction that they're supposed to be escorting the flock. Without the possession, surely they can make this batch of misfits someone else's problem. He'd just ditch them here but the last thing they need is finding out the possession retook them.

Weren't the Summoned helping to create dolls last year? Again: did not care about the dolls; did care about tinkering with the enchantments. He does not remember if those dolls and these dolls have any likeness in the slightest. (They don't). But in the way of magic they don't really have to, do they? The Summoned touching anything has a chance to eventually come back and screw with the rest of them.
