Yes. I bought a Samsung TV and there isn’t a way to set up Art Mode without the internet. So first you have to get a raspberry pi, install pi hole, then switch your router’s DNS.
What a wild experience 2026 is. But I do feel like a wizard.
They might hardcode DNS. It's not certain that this will work.

This does not provide any meaningful protection against data exfiltration. The TV is very possibly using public DNS or outright phoning home through stable IPs.
You don't need an actual physical raspberry pi to temporarily run pihole on your LAN, you can, for instance, install a barebones debian VM inside any common hypervisor on your laptop like virtualbox or qemu, then install pihole on that basic debian x86-64 system.
