There are plenty of conglomerates who are central companies who own a bunch of functionally distinct companies. Generally, each of these distinct companies have their own CEO and these CEOs will repo into the conglomerate's management structure.

I am sure in the case of Elon, there are de facto CEOs (and other leaders) at each of his orgs who effectively do the day to day management and report into Elon.

This is the reality - conglomerates like Reliance Industries exist and have very wildly divergent business units.
