Low oil pressure after service

The car should go back to that shop and have them figure out what happened. People make mistakes all the time, how they come through after it is what makes a good shop from a bad one. There is also the chance they didn't make a mistake either and you have another problem.

Could they have accidentally tried to drain the oil via the pressure relief spring and the spring fell out and they didn't put it back in properly or at all?
I recall another member on here accidentally did that when attempting their first oil change.

Cut open a metal case filter and you'll understand. On the inside it looks like the cartridge filter. Filters usually collaps when they get clogged.

Drain the oil via the pressure relief spring?

I'm trying to find the thread, someone on here went to change their oil but instead of undoing the drain plug they un-did the bolt that holds in the relief spring. Obviously they couldn't drain the oil like that but rather they thought that was the drain plug.
Perhaps they made the same mistake and re-installed the spring incorrectly causing low pressure?

Where is there a bolt?

I think you need to check this assembly to see if everything is there and spring looks ok
Check what oil was used then either change it or drain it and check the filter also and the canister as the bypass valve at the bottom can fail also!
Have the oil pressure checked with a mechanical gauge as your pressure sensor might be faulty
Maybe remove the sumo and check the oil pick up is clear.
Be careful about driving it as at this stage it could be an easy fix to restore pressure but if the engine runs without enough pressure it could cause major damage like cams being starved of oil and there are no cam bearings in these engines, the cams run directly on surfaces machined into the cylinder head, if they get damaged the head is scrap and it's going to start costing a lot
Not trying to scare you just be very careful!

Here's the oil pump... look under your rear bumper... you'll see this on the back of the motor...
The relief spring is under the nut to the right of the picture... it faces down when the pump is mounted to the motor.

Well dang, that explains the bolt I scraped on the asphalt the other day when going out of a driveway.
