Almost all ranges are propane compatible but will require the effort of installing the (included) propane conversion kit.

FYI, most of Whirlpool’s range lineup (including Amana, Maytag and the non-“Pro” KitchenAid models), all of Frigidaire’s range lineup, most of GE’s base line range lineup (not Profile or Café) do not have Wi-Fi capability. It’s mostly Samsung and LG pathologically putting connectivity into everything they make.

What features did you need that you couldn’t avoid connectivity? I just queried my own product database and came up with 202 models that are LP compatible and do not have Wi-Fi capability. And even among most of those that do (KitchenAid again being an irritating exception) you don’t need to connect to Wi-Fi or use the app for any functionality of the appliance; it’s just an extra.
