As another user of iTerm2, I am currently using several keyboard mappings from key to key (like Tab being interpreted as Esc), do you know whether Kitty supports that? As far as I can see in the docs, only examples of key to action are shown.

You could do that at the macOS level using karabiner for example. I have Caps lock as esc when tapped and Ctrl when held.
