If this continues, will maritime insurance keep paying out for these total losses? It seem untenable.

Some thoughts: 1) drain almost all the gasoline from vehicles so that if there is a fire, the fuel is limited.

2) for battery EVs, other than disconnecting the batteries, I dont see a way to make them safer for transit.

If we wanted to limit the spread of Chinese EVs globally, one way would be for shipping companies to tax EVs heavily for sea transport so that fires would be covered by the increased transport costs.
