do you lose benefits of templates if you no longer qualify for it?

The spellstitched template is from a 3.0 book, which was published before level adjustment was a thing. Figuring out what the LA should be is part of the minor adjustments a DM has to do in order to use 3.0 content in a 3.5 game. In other words, it's up to your DM what spellstitched's LA is, but you can't assume it's LA +0.
