The word "shot" in that headline is in the sense of "having been struck with a missile especially from a gun or bow." It does not indicate whether the shot was intended or a stray bullet that just happened to hit him. In that sense, I don't think that the choice of "shot" for that headline was specifically meant to be more attention-getting than "hit by stray bullet." It just happened to be the more factual word choice in the absence of solid evidence or clear indication that that Australian journalist was shot deliberately or accidentally. (Indeed, in the war zone that Marawi City has become today, it's really extremely difficult to tell.)
