None of the wisterias grow into a tree shape unless it has been trained that way. You can buy wisterias grafted onto a standard tree, which may be what you have. The leaves in the photo look a lot like wisteria but it produces long seed pods. If it is grafted, it is possible the rootstalk (standard tree) is growing and producing the round seed pods. Are you getting wisteria blooms in the spring?
The closest tree I am finding is a type of hickory. There are several native to Illinois if it just grew on its own.
