I think this is right, but I'm not 100%. The kettle should get what it needs, but I'm less certain whether a GFCI or ArcFCI breaker would have opinions that must be accounted for. I'll check with someone more qualified than myself to be sure!
Yes I understand. But what I'm saying is, normally neutral and ground would have roughly 0V potential, but in this case the UK neutral and UK ground will have 120V potential between them, because the US 120V second phase will have 120V potential to ground. (It bears noting that I am just a random guy and not any kind of expert. No formal education or credentials relating to electricity whatsoever.)
I think you're thinking about it on the kettle side, and I was thinking on the breaker side.
I think the kettle side would not care. It may be a ground fault in UK wires, but the kettle has no reason to detect it, and nothing sensitive enough inside to care. If I'm wrong, I'd expect to know shortly after starting the very first use. :)

They may not be 3 kW, but even the most basic of them are 2200W [0], and 3000W ones are readily available are not much more expensive [1]. They're also not really junk - they're a lump of plastic, a hot plate and a thermistor - the difference between a £8 one and a £80 one is almost all aesthetics.
I watched the video already before this HN thread, being a Technology Connections subscriber, but I genuinely forgot or missed that it discussed that aspect. I'm not surprised, though.
E.g, something like this:
