I have this very annoying vine that is growing all through my garden which I
can't kill.

If it's the one I'm thinking of, with leaves like crinkled sorrel leaves,
then getting the tuber is only half the problem. You need to find the
nearby source of the seeds, maybe a neglected garden or neighbouring wall.
This vine produces a prodigous number of seeds, they hang by the thousands
in decorative garlands. The young seedlings are very easy to pull out,
before the 6 leaf stage when they have yet to develop their tuber.

I expect that constant spraying of emergent leaves will eventually kill
off the tuber.
