I’m surprised there is no technical solution to shell-ing. Some kind of autonomous anti-shell gun that shoots them down mid flight? It seems like a fairly common problem.

You mean something like this one https://en.wikipedia.org/wiki/Goalkeeper_CIWS or the Iron Dome https://en.wikipedia.org/wiki/Iron_Dome

An Iron Dome was actually ordered by Ukraine but Israel blocked the transaction.

I hate their position right now... shows how unreliable partner to west they are when real SHTF

This will only work for a very unbalanced exchange though where the attacker has way fewer resources. The cost of an iron dome intercept will be far higher than that of an artillery shell. In an exchange of equally resourced opponents the attacker will quickly overwhelm the defense capabilities.

Physics will always heavily favor the attacker here. It's like a difference between throwing a stone at a target vs. throwing a stone to hit a flying stone mid-air with enough momentum to meaningfully change the trajectory. The second task is orders of magnitude more difficult to carry out

There is anti artillery radar, i.e. radar that helps position artillery so you can counterattack with your own artillery, drones etc. But it requires your own offensive capability.

Tanks have active protection systems. Practically they are little grenade launchers that trace and obliterate the oncoming projectile.

The "solution" is controlling the airspace so you can easily shoot back

Phalanx?
