this may help, but this trigger has point leak

This has no location leak, it has a group leak. And would not work.

Except for the event that he has in the above trigger that will work for selecting a random unit from a region.
Also this Unit - Kill (Triggering unit) needs to be changed to picked unit.

This only applies to region in the GUI context (JASS Rect). I do not think it is possible to determine units inside a JASS Region efficiently.
The process for getting a random unit in a JASS Region is considerably slower and more complex.
1. Rough enumeration of units in region. This can be as simple as all units on the map but the best fit would be all units in either the smallest bounding circle or Rect that fully contains the Region.
2. Filter rough enumeration to produce group of units in Region. Test each unit if it is inside the Region, discard if not. Best done using destructive loops due to the destructive nature of this filter process.
3. Apply random victim algorithm on Group of units in Region to produce Group of random units. GUI has one, although it may or may not leak.
Since most Region objects are constructed from a simple Rect, try and stick with Rect enumeration for maximum speed.
