integer ListXneqY(list lx, list ly) {
    if( llList2CSV( ListXnotY(lx,ly) ) == "") return FALSE;
    else return TRUE;
}

Example:

list l1 = ["a","b","c","d"];
list l2 = ["a","1","b","2","c","3"];
 
integer ListXneqY(list lx, list ly) {
    if( llList2CSV( ListXnotY(lx,ly) ) == "") return FALSE;
    else return TRUE;
}
 
list ListXnotY(list lx, list ly) {// return elements in X list that are not in Y list
    list lz = [];
    integer i = 0;
    integer n = llGetListLength(lx);
    for (; i < n; i++)
        if (llListFindList(ly,llList2List(lx,i,i)) == -1)
            lz += llList2List(lx,i,i);
    return lz;
}
 
default{
   state_entry() {
      llSay(0, "Are we different lists? " + (string)ListXneqY(l1,l2))
      //will say in this example: 1 , meaning yes.
   }
