Hello Craig:
I don't think there's a tool like this, and here's why:
Color Order Varies: There is nothing magical about the color of the stand vs. what it can be used for in a bundle. The color order 'standard' even varies into substandards! (TIA 568A vs B)
The bottom line: As long as an installer remains consistent, even a non-standard color order will technically work just fine. (Not advisable by any means, but true.)
Circuits Must Have Continuity: In order to check one end, both ends need to be connected. There are some very high-end cable certifiers that will tell you if particular strands are not making a connection or are botched up, but even those machines need both ends terminated to confirm electron flow is correct.
Checking both ends mean terminating them both, or your tech needs to be familiar with a toner probe to check bare strands, which usually takes more precision/skill than simply terminating the cable properly to begin with.
I'm not sure what LAN tester you have, but This checker is about $175 and tells you if pairs are crossed up:
If I were in your shoes, I'd get a device like this, and force my techs to terminate and check a bunch of 3' patch cables from a partial box of cable one day in between jobs. A 'rainy day' task, if you will.
Practice makes perfect. I think after an hour or two of crimping ends and checking them, they will be 'experts' in the field when it counts.
