Unless a leaf spring is physically broken, on a vehicle that light, they are probably ok.
Whilst the springs may be physically in usable, even perfect condition, springs with excessive lift may/can/will create multiple undesirable issues.
This vehicle reportedly has a three inch lift, which seems to have been achieved through the use of stiffer springs - this much lift requires a change in either the mounting points of the shock or the shock itself for one with longer open/closed dimensions to avoid damage to the shocks, as has already occurred based on the pictures provided.
A three inch lift will also cause bump steer unless steps are taken to compensate for the angle of the drag link, and last but not least, springs stiff enough to lift a vehicle by three inches, as these appear to be, will result in a significantly less comfortable ride than, for example, a lighter spring "arched" to provide the same lift.
There are other potential issues to be dealt with - bump stops may have been extended, drive shafts may either have been extended or spacers installed, caster angle issues that affect steering stability are what come to mind immediately.
Yes - leaf sprung vehicles are easy to lift - but lifting them properly AND safely is another matter altogether, and the more lift you look for the more challenging it becomes to sort out the issues - returning the vehicle to stock height or a minimal lift can remove many of the problems.
