Ok, I tried it, whitelisting it.
It was failing every 30 seconds and re-trying.
After whitelisting, the device did one lookup, succeeded, and hasn't attempted that address in the last 6 minutes now.
The only other lookup this TV did was to liberty.logs.roku.com, which was already whitelisted by the default pi-hole database.
How much extra traffic on my network and out to the web this will enable in the grand scheme of things...I don't know, but the thousands of repeated attempts all the time stopping would seem to put my mind at ease.
Someone knowing how I use my device, what I watch, etc. does not affect me in the slightest.
I am not using my Roku's to watch videos on how to overthrow the government, make drugs, etc., so I could care less.
I use my pi-hole to try and limit tons of traffic going out my network in the form of dns lookups in the first place, so I let the pi-hole resolve it locally, saving my router and modem from all that traffic. When something like this is blocked, and just ends up causing storms of internal try after retry from my 5 different Roku devices alone, I think just allowing it is actually better for both my internal network, and for my sanity.
