Seconding the comment above, I think "Loop" might actually be a technical term and something like "for each (whatever)" or "do X times" might be easier to follow. As programmers we know things like while loops and end conditions, but regular folks might want to see something a bit more human readable. Alternatively, maybe some kind of flow chart with a line pointing at itself might convey what a loop is - that end conditions are lines that leave the loop's outer box and otherwise the loop continues through the line that points to itself. I sort of feel like "loop" and "booleans" are technical terms that people don't understand as easily as simpler terms like "for each". I'm not sure how you could make something like "x < 5" simpler though. That's basically math and you might have to point folks to YouTube videos about inequalities.

Maybe you'd have more than one person setting this up - the engineer could write some of the details with the help of technical docs for the non-techie, but then someone experienced could provide someone less experienced with comments to follow or higher-level descriptions of blocks? E.g. At a high level there could be a human description that says "Load data: While there's more data to fetch ..." or "For each record, relabel fields..." but at a low level, it might say "While len(response) > 0, fetch data" or "Assign object fields x,y,z to response fields a,b,c".
