Sure, there's more complexity, but nothing crazy or intimidating. It's truly not much more than a battery and a few electric motors. It also deletes the alternator and starter (uses one of the electric motors for those functions).
I'll need to check again, but I am thinking there was one belt? Perhaps I should have said "fewer belt driven accessories" as they are electric and not belt driven.

There is a 2nd driveline present on hybrids.

There is no belt unless the engine happens to have a timing belt. Toyota's HSD is extremely reliable (I own one) but when they start to go wrong it can easily get to the point where the car has to be scrapped. Something simple like letting the traction battery go dead bricks the car.

And the inverter, inverter cooling pump, high voltage bus, rear motor, a bunch of current and load sensors, EPS, electrohydraulic brakes, battery cooling fans/system, all the controlling ECUs and datalinks for them, and I'm sure there are a few more things I'm forgetting that are added with a hybrid system.

It all just works. People don't need to fear them. It's a proven drivetrain. (I'm speaking to my own experience with Toyota hybrids. I haven't tried other brands.)

To work on a hybrid you need to be a mechanic and a DC electrical technician.
Your average shop is not qualified to work on these hybrids for anything more than "general service" and the smart ones won't.

There is one stretch belt for the engine water pump. Its original to the car still with no signs of issues

Engine wise one has the 2GR-FXE, the water pump is the only thing driven and I actually like that since it eliminates the need for a special water pump or electric drive head. Both of those things are very very expensive and water pumps by design are better off being mechanical due to the shaft seal always weeping ever so slightly. My Germans have 3 electric water pumps between the two and they are all known to have issues and I actually have a spare CWA100 pump in waiting for when the 4.0 has it pop.

I likely won't need to do much, the owner only intends to keep it 1-2 more years and after that I'll most likely be the next owner with this replacing my Jeep. I doubt it will ever give any issue past the traction battery and brake pump/accumulator
