It was quite a while when I last checked how exactly items are selected for the drop, but there is no fixed seed which is used to calculate the outcome. Unfortunately there is no detailed and accurate tutorial for item generation, https://diablo2.diablowiki.net/Item_Generation_Tutorial and other sources with that information are not accurate.
