I can confirm they exist, as one of the places I sometimes work has one - the base unit has a button for 70°/80°/90°/100°.
However, despite probably drinking in excess of 50,000 cups of tea in my life, I’ve only ever seen one of these kettles. The others have all been either “normal electric kettles” as you described, those always-on-water-boiler things you get in offices, or very occasionally, a traditional “put it on the hob or camping stove” kettle.

More to the point. They do not use temperature to do so. But instead use water pressure from the boil to turn it off.
Because water boils at different tempraturs at different altertudes etc. iE at higher altitudes the kettle will turn off at lower temperatures but the water is still boiling,

Yeah it matter way more to folks who like darker tea.
Water that is boiled allows the tanning to release more effectively. Hence tea made without boiling water thens to look whiter and even when colour is forced out with a spoon. Lacks the same flavour.
Tanning is also why tea has a calming effect. Mached with caffeine. It places the mind in a good state for problem solving. Hence the UK reputation of turning to it for all problems.
Well that and both tanning and caffeine are addictive.
