>What is the enhancement in mind? How should it look and feel?

For now, if no block is in range with the LoS placeholder, position is null, block id too... In a nutshell, that's an error message.
What if, instead, we made special results for finding nothing. Here's my suggestion:
LOC: Coordinates of the farthest air block in range in front of you. Then you can do something in the air and not on a block.
NAME: Air. Duh.
TYPE: 0:0
ID: 0
DATA: 0

>Please provide any additional information below.
Alternate solution: Make a functional placeholder that will not return the nearest block in front of you, but will return the block in front of you at exactly this distance, despite walls.
