Actually, when you recruit her, she says she was merely posing as one to try and get back the stuff the L bros stole from her, and that her real job is in sales.
Knowing Anna, she'd way sooner try to sell you an item than steal one. lol But if swiping something seems charming, maybe it could serve as an extra effect to another move. Imagine a Side B like Ike's that can't be charged as long or go near as far, but it can trigger skills, and also swipe an item if not holding a weapon/item. To make it even more effective it could even steal item effects. When your opponents grabs a star, just Side B them to steal the invincibility and hope a good skill activates. Imagine KOing an invincible foe at 0% with a lucky Lethality. Great for laughs, all the more reason people will prefer items off. lol
