Ted Lasso's reaction to hot tea is probably about the median US attitude toward it. We're just not used to it, and those of us who dive into that world usually have to kinda
acquire the taste through some effort, before we start enjoying it. Very few of us take our first sip of typical black or green tea and go "oh yes, that's delicious, I'd love to drink that every day". Black coffee's not far off, but it's more culturally
present so there's more pressure and opportunity to acquire that taste.
For my part, despite working at it for years, I still don't really like cheap tea (the stuff I could actually afford to drink every day, and that can be found without seeking out rare-in-the-US tea shops or ordering online), though higher-end tea is really good.
We drink a ton of iced tea, but that's easily made on the stovetop in a large pot, and can be bought in gallon-quantities at the grocery store. Having a kettle doesn't improve iced-tea-making very much.
[EDIT] Part of it may be that we drink on-the-go more than other countries. Just a guess, but might be true. Iced tea and coffee (hot or cold) are both much better for that than hot tea—one doesn't usually make a thermos-full of hot tea and drink it straight from the thermos, I'd expect (but maybe I'm wrong?) but that's normal for coffee.
