Do LV control cables have to be shielded? What is the downside if these are not shielded?

There is no code or rule that says they need shielding, it depends on the application.

RE: Low voltage control cables
The spec states the below,
LV Control cable shall be 0.6/1kV grade, and have stranded annealed copper
conductors of at least 1.5 sq. mm size, extruded PVC Insulated, extruded FRLS
PVC outer sheathed. Control cables shall be screened and grounded to eliminate
any spurious voltage pick-up. Cable shall comply with IEC 60754 Part-2.

My friends on oil rigs also like to see external armor braid to protect the insulation and shield from falling wrenches and such.

Interesting that the specifier used the IEC term screened instead of shielded, but then used "grounded", a typically ANSI term, instead of "earthed". Or in IEC terminology, does grounded mean something different from earthed?
