Must be Law that thinks he has a "questionable hit tool". Definitely pass - he was certainly right about Riley.
No, it's the fact that he hit freaking .250ish in college as a soph that makes his hit tool extremely questionable. Fangraphs, who you are quoting, has him as the 26th pick in the draft right now. Maybe his hit tool carries or maybe it doesn't, but you don't make top 10 picks on hopes and dreams. Langeliers looks like a guy who you take a flyer on in late 1st or the early second round, not a first rounder. His scouting reports read very similar to Lucas Herbert to me, who we drafted in 2015 in the second 2nd round and couldn't hit a lick.
1st round catcher picks almost never pan out unless they are in the top 4-5 picks of the draft. In the past 15 years there have been exactly 3 catchers picked after the 5th pick that have been marginally successful, Yasmani Grandal in 2010 (12th), Devin Mesoraco in 2007 (15th), and Jason Castro in 2008 (10th). Mesoraco has only had one successful season and Castro has been more of a platoon starter than a true starter during his career (though a superb defensive player). It would be a huge reach of a pick based on current draft projections, and it would be a poor pick based on draft history as well.
