I disagree, to a point. You could have one such 3-4 OLB, who strictly rushes, because, combined with your front 3, that's a 4 man rush, so Bosa would essentially be a 3rd and long/obvious passing down only player. If you pair him with Suggs, one of them is playing coverage or you are strictly rushing 5, which will get you killed if that's all you can do
I think defensive fronts and Bosa individually are both more versatile than that. I dont see any reason hed be more of a liability than any NFL OLBs.
