I tried to do this and just use my PS4 for apps, but my wife thoughtlessly accepted the TOS on the tv within 2 days.

We still don't use the apps on the tv though.

Disconnect it from your WiFi and change password. If you're not using the apps, there's no reason for it to be on your network, right?

I'm not sure that might be enough; it can still probably still "phone home" about when it's being used, what devices have been connected to it, etc. See if there's an option to factory reset it.
