You could extract it into a function inside the companion object:

class MyClass {

    companion object {
        lateinit var myGlobalLateInit: String

        fun isMyGlobalLateInitInitialized() = ::myGlobalLateInit.isInitialized
    }

    fun settingVariable() {
        if (!isMyGlobalLateInitInitialized()) {
            myGlobalLateInit = "I am set"
        }

    }

}
