While LoRa (the underlying protocol) isn't particularly EW resistant, it can theoretically handle a fair amount of jamming because of its insane processing gain. It is fairly easy to geolocate, but the equipment to do that is quite nontrivial at any scale.

Jamming against terrestrial radio is pretty meh, you need a ton of power and because of the inverse square law the bubble you can zone out is surprisingly small. There are also a lot of tricks to defeat it pretty soundly depending on the environment and type of transmission you're doing.
