LIDAR is likely not predicting RF so reflections should not be a consideration if it is just doing a LOS plot. Your image didn’t show where the site is so it’s hard to give a complete answer. Is it possible that there is LOS from a different site? Is it possible that there is just enough gap in the trees or obstruction that would allow coverage to that spot? It’s sometimes hard to tell why an area works if you cannot view the terrains/obstruction data in hill shade format so your brain can visually interpret the data. Is it possible that that part of the parking lot rises up in elevation such that it’s good enough for LOS?
If I were pushed in to making an educated guess just based on this image and no other input, I would say it’s coverage from a different site. OR it is quite possible the aerial imagery you are using is not in the same projection/alignment as the LIDAR data itself. When you get down to this resolute level of detail, different map file projection can shift things a foot or two here and there (including vertical ground elevation) that you can have what appears to be an inaccuracy.

Would the LIDAR collection be impacted by a reflection off the driveway (maybe it was wet and at at just the right grade to reflect)? This drive is fully obstructed by the outbuilding
