For the "coincidental encounter" maybe it's not so much "coincidental" as "the dolls were ready to be teleported to the tower where their target were located".

Another point to highlight is that Promestein designed them to fullfill an accurate role : Kill a heavenly knight each. For that end, she armed them with weapons specialized in killing their designated targets based on the data she collected. However, all datas were incomplete for various reasons.

For Alma Elma and Erubetie, because she didn't expect them to have hidden powerful abilities.

For Granberia, because she mastered a new technique that Arc-en-ciel was not programmed to counter.

For Tamamo, it's slightly deeper, since Promestein indirectly got screwed by Ilias on an epic level. She would have known more about the ancestors than just the way they were sealed, she would have learned about Tamamo and may even have prepared more accordingly. It means a lot about how much Ilias had an absolute trust in her plans.

So basically, Promestein screwed up because heaven's force's leaders were too busy using and stabbing each other thinking they already won to follow new developments on the surface.
