I'm not familiar with AutoCAD, but LibreCAD has construction layer feature.
It was called 'Help layer' in past:
https://wiki.librecad.org/index.php?title=HowTos_and_Guides#Help_Layer
And is called 'Construction layer' now:
https://wiki.librecad.org/index.php?title=Layers#Construction_Layers

Draw any line, any direction, length doesn't matter. When construction layer attribute is switched on, all lines become infinite.
There's an icon in layer list to toggle it.
