I did the same. Roku is extremely chatty. It's easily the most chatty device in our home (thousands of connections per device outbound to their telemetry per day). It didn't take much time to block everything and then gradually figuring out which was absolutely needed for the level of functionality I wanted. Everything else gets dropped on the floor. Roku gets "desperate" and demon dials home base when you block connectivity to the data harvesters. Luckily only the small raspberry pi needs to be involved to squelch the noise.
raspberry pi 4 + argon case with M.2 SSD + ubuntu/debian + pihole
The whole thing took maybe 45 to setup and then another 45-60 mins of trial and error to shutdown the unwanted connections. Every device in our home uses it for DNS resolution so all the "smart devices" can be squelched from one place. It works very well for me. YMMV
