I think it's the normal behavior of Minecraft.

When I coded the rndtp mod, I expected to have to check for all trees wood and foliage in order to put people safely on the ground, but when teleporting into an ungenerated chunk, when you place the player at the destination before sending the update to the player side, the terrain is not "populated" with trees and other "decor" so it's not necessary.

Of course, for players teleporting afterwards at the same location, they might appear on top of a tree, but it never happened in my tests.

When you add the LOTR mod, the only additional effect was that the mod could decide to build a structure just at your location, and you could find yourself underground. It happened to me a few times in Mordor.
