Question

Is there another component that works just like a Logic Or Gate that is not a microchip?

Answer 1

Sure, an array of electromagnetic relays can be arranged to act as a logic or gate.  

Similarily you can use vacuum tubes as they did in the early days of computers before transistors were invented.  

If you do not consider individual transistors as a "microchip" then you can design a circuit using individual transistors to be a logic or gate.

Answer 2

A transistor or diode can act like an OR gate. Or a bank of them.
