When it comes to TVs you can buy in a big box store today, I'm not sure there are any TVs that fulfil your requirements. Everything's more or less on a scale of privacy to quality, where on one side you have the panels of 10 years ago with dumb electronics from brands you've never heard of, and on the other side are the LG panels, but with LG non-privacy. The other notable brands you've probably heard of fall closer to LG than to the no-name brands.
You can probably scrounge up a decent modern-ish panel on the used market that's old enough to not have been shipped with malware, but then you're betting on it not having been updated to receive the malware, or relegating yourself to rooting it the instant you get it home.
My unspoken assumption is that you don't want to give money to evil companies. If you yourself are fine with giving your money to evil people, then you can Just™ buy an LG panel and root it.
