I'm still not clear on what you're trying to accomplish. I thought you were trying to get HOT for a given lat/lon pair. In this case, there's only one intersection. From your last post, it sounds like you're tying find intersections with the terrain for a given LOS between two points. Is this true?
A couple of questions so that I have a clear understanding... 1) Why would you want to have the lower LODs available for doing collision tests? You always want the highest LOD for doing intersection tests with the terrain. 2) What are you using for doing the LOS check between the line and the terrain? Are you using your code snippet that you posted earlier or are you using osgSim? You should be using the methods in osgSim because it pages in all the tiles you need to check for intersections between two points in the case of LOS on terrain. The highest LOD for each tile that lies between the two points is what you need for intersection testing...
