Aren't roku devices notorious for gathering data on how you use their hardware and what you watch? In fact as far as I know you can't even use their TVs without actually creating an account with them. If this is still true, it's completely NUTS!
When you set up a Roku TV, you have the option to never connect to the Internet and use it as a dumb TV. In that mode, no WiFi or Ethernet connection is active and there's no connection to a Roku account.
If you've already connected the TV, you can factory reset it to an unconnected state.
You're placing too much trust into the effectiveness of pi-hole and its associated filter lists. Here are some failure modes I can think of:
* using fallback hardcoded IPs when DNS fails
* using DoH so it's impossible to tamper with the response
* using the same domain for spying as other critical functions
* new domains might not show up on the filter lists right away, and if the TV keeps a backlog of failed requests, all your viewing history might be uploaded when that happens
