had the same issue with one side xreas "shock" on mine. (these arent struts)
no need for a sawzall or cutting torch, the body of the shock is stuck in the hole of the shock tower... get a long beefy crow bar or pry bar & wedge it in between one of the top spring coils & the inside of that shock tower, then pry side to side & downward with as much force as you can manage to dislodge it, it should pop out. also try to hit the top of the shock & the 3 bolts with a hammer to help break it free. & make sure the lower control arm is pushed down & not touching the bottom of the shock helping to keep it in there.
if you havent, use some penetrating oil around that whole area to help & if it still doesnt come out try some heat on the outer area of the shock tower hole, not on the shock itself. i suggest a propane torch as the flame is smaller & not as hot so no risk of damaging other parts or catching the vehicle on fire!
but you shouldn't need heat, prying in the right area with the right angle & amount of force it will come out, its just light rust/corrosion holding it in there & its not seized or welded in place from the rust.
