Maybe the tech didn’t to the re-sealing on your rack properly. There may be a seal he used which Isn’t the required size on a high pressure pipe where the fluid flows through which is creating a blockage. Either that or he has tampered with the actual gears in the rack and misaligned/damaged them. I doubt a tech who does that as a profession will knowingly make such mistakes.

But of course the above only comes into play if he initially didn’t touch your power steering pump and all the hoses were properly tightened and bled.

Yes. There might be a blockage. There are many pipes where fluid flows through both inside and outside the power steering rack. Once any of them collapses there will be issues.
