IMO this is one of the very few "good" use cases for herbicides. Glyphosate works. If you don't want to spray, triclopyr ("Cut Stump and Vine Killer") can be dabbed on the cut woody stems at ground level. It's a pain for a big area, but it works, and it doesn't touch anything else. Winter's a good time to do it.
