Which sound as part of the english on system but not a part of the spanish sound system

In spanish 2 L's together makes the y sound. Like rollana in spanish sounds like royana, and y by itself means "and" but its pronounces sounding like e. So, I would say the double L sound, but sh is non existent too, so maybe it is sh, maybe I misunderstood the question. It probably Sh most likely
