A very basic question:
The end of lightning cables that plug into the device can be inserted either way; there is no right or wrong way.
Why can’t the end that plugs into the charger be designed the same way?

They are USB at the other end, which is not a standard developed by Apple.
This allows you to plug your phone to your computer without needing an adapter.

Except if it's USB-C, which is similar to the way Lightning works, i.e. USB-C is bi-directional, so to speak. (distinguished by its two-fold rotationally-symmetrical connector)
Apple sell Lightning to USB-C cables for around $35 (yikes!), but of course, you need a USB-C port on your computer or charger.

A practical question: if a cable isn’t direction neutral, why not put something unsubtle, like a red dot, on one side?
That wouldn't be any good, although USB (1-3) have a USB logo on one side of the connector which should face the male part of the input port. Bear in mind that USB (1-3) ports can be horizontal or vertical.
You only have to look, really.

I'm afraid you're stuck with checking the rotation. It's a pain, but there it is.

You can always draw a mark with a marker or add a drop of nail polisher so that you can feel the raised drop.
My home key has a raised dot on the upper side.
