LoRa doesn't have to be LOS, it depends on the carrier frequency you use. 900MHz LoRa is used for building penetration of control signals for racing drones, for example, with the open source ExpressLRS system.
I have a bunch of (low powered, runs for 24+_hrs on a single 18650 cell) 433MHz Lora/Meshtastic nodes - I can get 10km or so range with simple 1/4 wave dipoles indoors in urban environments. Hills kill it a bot, but I've got one shot that gets 3.3km non line of sight with a hill between the nodes.
