Since Lightroom is basically a global image editor, and glare removal takes pixel-level editing, your conclusion is correct. Either Photoshop or Photoshop Elements can do that job, but not Lightroom. If the glare isn't too large you might be able to touch it up with the clone/heal tool in Lightroom, but probably not.
