I just built my first LiveView app in anger last month. I don't really what you mean, though.
If it helps, I built my app the same way I would have built a Rails app:
1. Create a migration and some files to map DB tables back to my app
2. Create views and wire them up to the database
The automagic was 80% of the automagic in Rails. LiveView isn't giving me automagic, exactly, it gives me a way to interact with the browser.
One reason I may not understand what you're saying is: I didn't design my application architecture. I started with a small part and just built the rest incrementally.
