How would I replicate Gizmos.DrawLine in-game?

I really need a way to draw a line in-game. The Line Renderer is not suitable, because it automatically rotates towards the camera and you would need dozens of line renderers if the line is not straight, otherwise it would start twisting. ]

I have heard of certain paid addons but I cannot justify spending money on something as simple as drawing a line. It seems very odd that Unity has a seemingly perfect line drawing tool limited only to the editor. Is there any way to replicate this in-game?
