For their next-gen Fleet IDE though, it looks like Jetbrains is using Kotlin and Skia/skiko?

Fleet does not use Compose, but it does use Skiko[1], which also provides binding for Skia[2] (the native graphics library also used by Chrome & Flutter).
The main difference between the libraries is that Skija provides Java/JVM bindings for Skia, whereas Skiko provides Kotlin bindings for Kotlin/JVM, Kotlin/JS, and Kotlin/Native targets. Of course Skiko's Kotlin/JVM bindings can be used with other JVM languages, not just with Kotlin.
JetBrains Compose UI is using Skiko, not Skija: https://github.com/JetBrains/skiko
Compose also draws to skia https://github.com/JetBrains/skiko
