LVA is a LTD. Same thing different name. Matching does not seem hard. They can infact match to more or less all sorts of different loads as well as anything else can. Pulse times from micro seconds to ns are also fairly typical. They however are not that cheap. The ferrite tends to be the bulk of the cost. More so if you go for metglas. However it does offer a way to add smaller current and voltage modules that could use solid state switching to more or less the MA levels and MV levels (add a transmission line transformer for more design flexibility too). For a commercial operation the extra capitol cost could well be justified.
