Are you playing with gyro aiming? I also loved the gameplay of the first one and was disappointed by the second. My hypothesis is that aiming without gyro was too tedious so they updated the gameplay to require less aiming. Not that the game tries to be realistic anyway but the combo/special attacks and the time spent in the inventory/wheel kinda break the immersion/flow for me.
From my understanding, AI is the general field of automating logical (“intelligent”) tasks.
Within it, you will find Machine Learning algorithms, the ones that are trained on exemplar data, but also other methods, for instance old text generators based on syntactic rules.
Within Machine Learning, not all methods use Neural Networks, for instance if you have seen cool brake calipers and rocket nozzle designed with AI, I believe those were made with genetic algorithms.
For procedural generation, I assume there is a whole range of methods that can be used:
