Has anyone had any experience with this sort of situation ?

Yes, a persimmon tree nearly drove me to drink for a couple years at
MIL's place. Talk to your local agricultural agent about spray
herbicides. Today there is Image and it won't hurt most lawn
grasses, like Roundup, (Roundup kills almost everything.) but it does
take some time to allow the herbicide to work and the lawn looks
pretty neglected until it is finally ready to cut again. Image won't
kill crepe myrtle and several other shrubs, but these usually aren't
the kind of culprits you are talking about.

There is also Weedeezy:

This allows one to spot treat without the danger of overspray using
Roundup.
