I've never heard of snails eating live plants, except the Apple Snail,

You may be right, the thought of snails not eating plants never
occurred to me, but I can't believe they add anything to the pond
except a snack for koi and the occasional parasite. I think I would
like to remove them completely, and I don't think fish will be able to
do that. I realize they may be transported in again, but I'd like to
start over.
