Engineering tends to mean "the application of scientific and mathematical principles to practical ends".
I'm not sure there's much scientific or mathematical about guessing how a non-deterministic system will behave.
The moment you start building evaluation pipelines and running experiments to validate your ideas it stops being guessing
Funny how you use a scientific term to discredit applied statistics. I've built useful non-deterministic systems many times and they had nothing to do with AI. Also, particle physics would like to have a word with you.
