And that's clearly documented for mksh: in the mksh(1) man page:
kill-line: KILL (^U)
Deletes the entire input line.
Ditto for ksh93:
kill (User defined kill character as defined by the stty(1)
command, usually ^U.) Kill the entire current line.
And for zsh:
kill-whole-line (^U) (unbound) (unbound)
Kill the current line.
