Assuming he shoots some kind of magic bolt from a distance at the plant that turns it into the sheep, if you can see the bolt traveling all you would have to do is place down a low cost plant (Iceberg Lettace, Puffshroom, Sunshroom etc.) so that THAT plant will turn into a sheep, instead of your important plant.

However for endless zones, I see no hope.

If he works like the Explorer zombie where he has to be right next to the plant to transform it, then we have nothing to worry about.
