Our Retirement Home Thermador Cooktop [seriously 'macho' and Pro for Da Wife's use] has 120 VAC circuitry that senses Flame presence.
Double check your assumptions to not be disappointed and understand in a given Cooktop Model what role the 120 VAC Circuitry plays. As an example, a little breeze from a cracked-open Window adjacent blows out a Simmer-level Flame on this Thermador, which auto-relights immediately.
The consequence of a Flame going out is very different inside were the Propane to keep flowing. Manufacturers of the Cooktops you're looking at would have to incorporate that reality into their Control designs to avoid Lawsuits.
Not you'll be in this situation, but I put a Surge Protector on our Cooktop. When I saw the complexity of the PCB at Cooktop installation, I realized Lightning could take it out [$$$!]. This happened to us on a newer Fridge w/a densely-populated PCB at our Mountain House.
