Hi Mdkrause,
So sorry to hear this.* Hopefully you took video or pictures before, during and after.* Sometimes trees will survive such treatment, but trees tend to decline slowly from such an experience and it could take 2 years or more before you see the effects of the crown beginning to die, if that is what will happen
If it were my tree I would have a certified arborist take a look at it when it leafs out this spring.* They might want to add beneficial micro-organisms or fertilize it to help with root regeneration.

When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
