It is called - but it's very very rare that the call has to be made - if the runners position out of the running lane doesn't affect the throw or catch of the throw, interference is ignored. You don't call RLI simply because the runner is running out of the lane
Because of the geometry, the throw has to be coming from the vicinity of home plate.
Additionally, interference is a judgement call 99% of the time (the exception being if a runner is hit by a batted ball in fair territory, including while standing on a base). Just like a ball, strike, or half swing (the only true judgement call that can be appealed)- it's a judgement call and is up to the umpire as to whether or not the batter runner or runner impeded the defense's ability to make a play - intentional or not.
That's what a lot of people are struggling with in terms of the rectitude here. This ball wasn't really anywhere near home plate. When Peacock fields the ball, he's in line with the end of the World Series logo on the 3B side, at least 15 feet from home plate. You're giving the fielder the benefit of making a terrible throw, because a good throw maybe doesn't get an out on this play - and certainly doesn't send the runner back to first.
I pitched a lot and played a lot of 3B, so I've fielded a fair number bunts in that location or close to it. I can't recall a runner being a factor in a play even though everyone runs outside the line. They're just not anywhere near your line of sight when making the throw, so it only matters when the collision actually happens. And by that point, Turner is so close to the bag that he's exactly where he'd be whether he'd been in the lines the whole way or not. What I'm getting at is I can't really see how a reasonable person would think him being out of the line affected the play.
I understand that may not play into the decision based on the actual text of the rule, but it's a really rough application: Turner's being out of the baseline on the way down the line shouldn't be affecting a throw from that far up the 3B line, and if he'd run in foul territory the whole way he'd still have had to come fair in the location the ball hit him as he hit Gurriel. I just can't see how any application of judgment ignores that.
