Sure GG has LOD: GG is designed so it use culling instead , by splitting up the terrain in smaller pieces , so non visible terrain can simply be culled. Also GG use detail LOD so when you move your sliders GG will reduce the details depending on the distance you set. If you want to see the LOD in action , set the terrain shaders to Highest , and try to play with the LOD sliders, you can then see how the details change in the terrain.
I think this type of LOD is called node based , but who knows it keeps getting new names
