Don't know the LS specifically, but lots of times the hook, or U the hook attaches to, is mounted with bolts in a slot or larger holes allowing slight adjustment. Sometimes you may even need to take pliers and bend it slightly till it catches correctly, or maybe on your's the latch is adjustable. On my new Kubota, it doesn't want to unlatch when it gets real cold. I sprayed it LIBERALLY and it pops right open now.
Unless as Bob77064 has stated his also is misaligned, maybe the hood itself is not in place perfectly and it may need to be removed, then reinstalled making sure to line everything up as you go SLOWLY. Kubota website has diagrams of model's parts in blow-up view, maybe see if LS offers the same and try to find the part on the diagram that's adjustable. Hope this helps, once again - good luck. Post some pics of catch, hook and mounts.
