I'm not sure I understand what your usability problem actually is,
but to kill a less without input you can hit "ctrl-z" to put it in
the background an kill it with "kill %".  This will also kill the
background pipe process if it's listening to signals. (I.e. a
sleep will survive, but normal command won't.)
