I've had that happen to some URLs I own before. Basically, they forgot to renew. Normally you get a grace period but some sketchy domain admins take the lapse as an opportunity to auction off what was originally a worthless address now that it has value.
If you are not able to find a dumb TV, I recommend Google based TVs (GTVs). Unlike some Roku based TVs, GTVs will boot and work just fine even if you never configure their network access. If you do opt to enable network access on a GTV, you can set up static IP addresses on them, including PiHole as DNS.
My wife likes the convenience of a smart TV in her office so I DMZ'd it so that it has no access to our home network and it goes through a dedicated PiHole on a Pi Zero. Neither the Roku or LG TVs we had allowed for this, so I sold the RokuTV and I connected the LG to a thin client with a Bluetooth remote.
PS: Hisense makes a great 4K TV that goes to shit the moment you connect it to the network because of inadequate computing power, low memory, and bad code (memory leaks). If you don't connect it to a network and use it as a dumb TV, it is great display for very little money.
Although I agree, I think AI code generation is the follow up mistake. The original mistake was to offshore coding to fire qualified engineers.
Not all of offshore is terrible, that'd be a dumb generalization, but there are some terrible ones out there. A few of our clients that opted to offshore are being drowned is absolute trash code. Given that we always have to clean it up anyway, I can see the use-case for AI instead of that shop.
