Could you quote a non-trivial "systems thinking" theorem or tool such that, by knowing it, I will be able to solve a problem I couldn't solve before?

This is totally orthogonal to your original claim that systems thinkers are "liberal" philosophers but OK.
McCulloch and Pitts, early cyberneticians literally invented neural networks. See the wikipedia page on neural nets.
Another really simple one: Law of Requisite Variety. If that's too simple, I'd encourage you to bear in mind that Norbert Wiener, beyond his direct contributions to mathematics in the form of signal processing filters, is also responsible for the view of control as communication, which motivates much of the approach to control and stability in digital systems.
The entire field of process design & automatic process control. This literally is the O.G. job description of a chemical engineer. The field of grid design and balancing. Again job description of an electrical engineer.
Yes, but in all your examples it's the same: you learn the specific subject and you are implicitly learning "systems thinking"; it's not like you learn "systems thinking" first as the hard part, and then you learn electronic components as an implementation detail to become a electrical engineer.
I see your point. Indeed we do learn it bottoms up. But why do you think the opposite is impossible? It seems like a transferable skill across domains.
Here's one: reading the most basic Wikipedia page about a subject before you make up your mind based on your political ideology instead of any actual knowledge.
