Just like the Tribunal teleport blocking is available under https://openmw.readthedocs.io/en/latest/reference/lua-scripting/openmw_types.html##(PLAYER).isTeleportingEnabled, this request is for a similar access to checking/changing the levitation block. It seems to be controlled by openmw\apps\openmw\mwbase\world.hpp's MWBase::enableLevitation and MWBase::isLevitationEnabled Unless it should rather be in the world Lua range, not types.Player? Up to implementation and followup discussions.
