Beginner Gardening: apple trees, 1 by gardensquare

We just planted a bunch of apple trees and discovered they have Cedar Apple Rust. There is a big cedar tree in the midst-we will cut it down. However, we also have established Leyland Cyprus trees close by. Will Leyland Cypress trees also cause Cedar Apple Rust? I can't find it listed that they do, so I don't "think so"; but they are so similar to
Red Cedar Trees ~ I thought I should ask.
Oh boy, if we had only known "before" planting. (sigh)
Any additional hindsight is greatly appreciated!!!
