For that, you might try Boroda74's "additional tagging tools" plugin.
I can't give you a step-by-step tutorial, but I am pretty sure you should be able to achieve something like that with it.
Either by using some formula, or by perhaps (temporarily) copying the titles to the artist field (of which you can remove 'The' from displaying)
(And before doing that of course storing/backing-up the actual artist field in a custom tag, so you can always put it back.)
If you are going to experiment with this, be sure to try it out on some copied files first, before using it on your actual music library.
