Nope, no patch yet, sorry. And I've tried to solve it by myself with the console and following several tricks people mentioned, but none have truly worked for me yet. MarkForDelete just doesn't do it for me. And yeah, aside from the five Letrushes I've got standing at the Whiterun stables for the third time, the amount of times I've encountered him in the wilds isn't countable anymore. Louis running along the path, Louis attacking an ice wraith, Louis in a fight with a spriggan and a bear, Louis running away from no apparent threat, Louis meeting the orc for the umpteenth time and getting killed (tried to save him once. Bastard said thankyou with his little knife. Replied with the same, in a bit larger shape and twofold). Last time he got killed by the orc in Riften, after which the orc entered the Barb and Bee where Maven sat, and left it again.
how do you kill him?
i have this glitch and he's marked as essential
He shouldn't be essentail after you've done his quest. Both the ones at Whiterun stables as the ones yoou encounter over the world are killable. Doesn't stop them from reappearing 'though ...
