I typically build webapps using .net/angular/node/whatever. But I want to try build a landing page website using wordpress and elementor.

I assume a “theme” is similar in concept to a ui framework (e.g. bootstrap / material design), with some typography, css presets, js widgets, etc.

Therefore, if I’m using elementor (and building a page from scratch), does that mean I still need a theme? Can I disable all the themes that come with wordpress?
