This should work, but please note that I didn't test it. Better make a backup of your entire library before you try it.
Select the books you want to change and then "Edit metadata in bulk". Go to "Search and replace". Set "Search mode" to "Regular expression" and than select "title" as "Search field". Enter "^ " (note the space after the caret) into "Search for". Leave "Replace with" empty. You should see a preview of the first book titles at the bottom of the dialog. If it looks right press "Apply" and you should be done.
If some of your titles start with multiple spaces change "Search for" to "^ +" (again, note the space).
I'm not sure, if this also updates title_sort, but I hope so. If not, you can try to do the steps above again for "title_sort" but this may not work in every case.
