Depends what all you installed using LML. I don't know how LML handles file extraction/installation, but I use EMF for OpenIV, and that works without fail for everything. That in mind, however, it might be worth a peek to see if you can't find the files it replaced using OpenIV, and then use the ones from the original game directories to replace if required. This is how I fixed several issues in the past.
It's not overtly difficult, but it is tedious and a long process.
