Thanks a lot Sergio. As a workaround, I simply removed the hunspell package and installed myspell-en-us. I was then able to select "American English (United States) [US]" in the Spell Check settings. When I reopened Kate, spell checking worked (though I confirmed that it was using the right dictionary in the settings).
