Wait until Part 3.

There's already at least one weapon (Sword of the Heavens) and another storyline weapon (Angel Halo)  that's only usable by Luka,  so its unlikely that they wouldn't eventually make him the strongest character in the game. He is the MC after all, and the Hero Protagonist trope applies to him specifically.

The last blog post indicated that there aren't going to be any straight-up buffs planned for Luka (like what they did for Illias) at this time for Part 2. Players will just have to "deal with it" for now.

But they mentioned that there will be Heroism-specific skills that can be learnt in the upcoming Part 2 LoC which should even the level a little bit for Luka and any other companion that can use Heroism skills.
