Do a search for "Blender GPT" there are several efforts ongoing. I've tried a few, and it is exactly what you describe: basic 3D shapes, some basic rigged objects like pose figures and blocky vehicles. Just put them roughly where you want them, likewise with the camera and lights and write your prompt. It's kinda ridiculous how fast and easy and, well, disposable all this is.
