Couple of things you can check, in the Kasa mobile app they would say "Local only" under them if the cloud binding is off. I will add a screenshot from my phone in a minute. The app author has mentioned some newer models do not allow the cloud binding to be disabled anymore, thats why he made the cloud integration in the first place I think.
Also if you enable debugging for a device and send it a command, check the logs. Mine I can see it says sendLanCmd with the IP
Last thing you could try is to clear out the cloud config so that it cannot even log in anymore, thats what I did with mine so the only option for the Hubitat app is local control.
You might need to go into the utilities section and clear the DB then re-discover the devices to get rid of the "CLOUD" in the DB entry, not sure. But if those are some of the devices that only work on the cloud then it wont help.
