>you can wager by deciding which item to buy

This is the flimsiest argument I've seen for this so far!

For the record, Luck Be a Landlord's items and symbols do not cost money.

But if we followed your logic, any game that has a shop you can visit multiple times has a gambling feature. That sounds kinda silly to me.

Of course it's silly. I think the game is great and fun (and ... humans can get pretty enthusiastic about fun games ... to the point of putting off other things so they can play said game ... oh noes!), and Play/App stores are their own special hell, so best wishes for the devs, yet ... I think the policy applies to this game. (And likely to others too as you point out.)
