If you kill them, in 5-10 years their roots will rot and they will
fall over. If you don't, they will regrow and be as much trouble
in 5-10 years.

I have never known Leylandii regrow from the trunk, only from
remaining green growth.
And if you get 5 to 10 years of use as a support then that's not bad
as most posts used for the job would only last that long, and by then
you have no problems with having to dig out the stumps.

That is what we did at our old house. The previous owner
had a row of Leylandii as a hedge, but prior to selling had
cut them off at 6 feet. They looked awful. I finished the
job by removing all the side branches and using them as
fence posts. I fastened some chain link fencing to them (to
keep our dogs in) and planted up with a mixed hedgerow of
pyracanthus, hawthorne, holly and berberris. After a few
years it looked really good and the tree trunks and chain
link were invisible, lost in the hedge foliage. The trunks
made no attempt to re-grow with the exception of one trunk
which produced a half hearted shoot then died.
