What are your requirements exactly? If you want a touchscreen built by a vendor to be used/linked with HA, that is one thing, if you simply want a touchable-screen there are many options, ranging from old or new ipads, Android tablets, fire tablets, complete touchscreen monitors, custom built projects (often on a ESPHome basis) and even devices that check if you tap on the wall to turn things on or off.
If you want a physical switch with some basic information check the Aqara display switch 1 or the smart S1 scene panel.
