The practical solution is to generate several CSV files and distribute work at the granularity of files

Sure, now you need to do this statically ahead of time.

It's not unsolvable, but now you have a more complicated system.

A better file format would not have this problem.

The fix is also trivial (escape new lines into \n or similar) would also make the files easier to view with a text editor.

But in practice, you’ll receive a bag of similar-format CSVs.
