Every since I move to this house (10+ years) we've had this problem.

There's a large (40 ft?) tree in the neighbors yard behind us that
sheds jillions and jillions of these tiny leaves in the fall --

Those are the seeds of an elm tree (_Ulmus_ species).

I have no suggestions about what to do about them other than learn to
live with them. Elms are one of the most popular shade trees in North
America - for good reasons. However, in many areas they have been
attacked by Dutch elm disease (a fungus spread by a beetle).
