I guess one should first ask "how smart" a stove it is (Brand / Model).. although it seems a bit dumb if it won't accept almost any reasonable AC waveform. Maybe the supply for the electronics in the smart control circuitry needs a bit more supply filtering (eg more electros to smooth out any voltage changes) if a conventional supply or a wider input range rated SMPS.
The "They have a 240v stove (which has some internal electronics for various functions) that will run OK on the 12v system with a 12v > 240v inverter, however it will not run on the generator. " is an interesting statement in itself.
The in-line filter option doesn't really seem feasible as it would take multiple stages of quite high power level low pass filtering to sine-up a (possibly near) square wave. Then comes the safety concerns about construction of a 240VAC-based device. A commercial filter is likely to cost many $$$$ if available.
The switch-on current should be the same as the run current as they are purely resistive elements in a conventional stove. The specs of the stove should show power consumption values for each element setting.
The best suggestion is to go back to one of the old style stoves that has just heating elements and mechanical power switching. They will work provided that the genny produces around 240V on-load.
