I haven't encountered anything like that, but one thing you didn't mention trying is the ordinary Rename command. See whether this works to give you something you can purge:
(command "_.rename" "_style" "" "whatever")
or try the equivalent with hyphenated [so it doesn't give you the dialog box] -Rename typed on the Command: line. [Or, it's just possible that it would show up in the Rename dialog box as a blank line, which you would probably need to pick on to know it's there.]
As an aside, I'm curious to know how you were able to pin down the "" Style name in the first place....

....the problem text style that's referencing it has "" for a name. Naturally, it doesn't show up in the style dialog. I've used tblobjname to find the table entity and tried to change the name, tried to delete it, no dice. Tried using the vla functions to delete it or rename it, also no dice. ....
