This looks like some type of mildew, is it serious? If so, is there a way to treat it?

Yes, this looks like powdery mildew, which they can get when they get too much shade.

Here is information on that: https://www.clemson.edu/extension/county/laurens/mg/askmg/047_leyland_cypress_trees.pdf

You may want to thin out your Leylands or remove other plants that keep them in too much shade.
