Does any class or mythic path get a "Smite Lawful" power/spell?

[Asgar]

I've noticed you can smite Good, Evil, and Chaos, but I haven't found any ability to smite Law yet. Not that it will find much use with all the Chaotic Evil enemies, but it would suit the roleplay of my current run.

warpriest champion of faith should be able to do that since the class is pretty much just smite anything that isn't your alignment.
Other than that no class, even in pnp, has the smite law feature, it doesn't exist, since there is no chaos champion (unlike paladin hellknight and antipaladin).

There are quite a few anarchic weapons in the game that would do extra damage to lawful beings. Also there's a word of chaos spell which would blast lawfuls.

... unfortunately, like the unholy weapons, which damage good, there just isn't very much to use them on. Well, maybe unless you go swarm, and decide on the war of you against all.

AFAIK "smite" feature emulate some dedicated training to fight evil/chaos/good. That's why chaotic creatures are do not bother with it - wasting your time doing learning, huh?

Remember Storyteller history - as elf (CG/CN) he isn't locked inside his tower and studied magic. No, instead he gonna adventuring all around.
