LaL does not fix it as really fix it. It just gives you a way to avoid it caus vanilla start is heavy scripted. Something most bigger and scrpited mods tend to destroy. I would rather disable all your mods except LaL. start from there and try if it works fine. Then enable a couple at a time, start your game play a little and so on. Its annoying but the easyest way to figure out what causes the crashes. If LAL does crash on its own i would suggest maybe Realm of Lorkhan, another LaL Mod but a little different.
