I wouldn't reinforce it, you want that tie rod to be the weak link if something applies a lot of force to the steering mechanism.
One time I had some tie rods that kept bending, so I replaced them with upsized titanium ones...the next thing I knew I was breaking steering arms and kingpin holders. Ok, so that was on my r/c cars I was racing but the same rules apply, you want the cheap, easily replaced parts to fail when needed to protect the expensive, hard to replace pieces.
