6♦ was rock solid but 7♦ was not makeable, and I lost 11.9 IMP as a result.

I didn't open 2NT because of my unstopped ♥, and the robot pushed me to die without even checking all 5 keycards were held.

7♦ is ridiculous, of course, and comfortably the worst bid, but those that play with the robot quickly learn it will almost always jump to slam when it has values and you show a strong one-suited hand as you did. (Usually an immediate 6NT when it doesn't have a fit).

But I don't understand the appeal of emphasising the diamonds to begin with - the only reason I might not open 2NT is if I thought it was a little too strong, in which case I'd open 2♣ - 2♦ - 2NT instead.

You asked who's fault, it's your fault. 2c followed by 3 of a minor show a very different hand than what you had. Once you misdescribe your hand, you are responsible for every bad decision your partner makes as a result.

Yep - the clue is 23+ total points plus you need to know your notrump ladder by rote and bid accordingly.
