I've seen conflicting reports as to what stage of "Dragon Rising" initiates the random dragon spawning mechnism.
elderscrolls.wikia appears to indicate that they begin spawning as soon as the quest starts via its suggestion to put of completing the previous quest "Bleak Falls Barrow".
Meanwhile an answer to a question on arqade appears to indicate it occurs when the first dragon is slain. As does uesp.net.
Am I simply misinterpreting what elderscrolls wiki is suggesting or is one of these wrong?

They start showing up after you kill the dragon.
I believe you're misinterpreting what Elder Scrolls Wiki is saying.
The first part of this quote makes it clear that it is talking about completing the quest. It says you should avoid completing it because the dragons can be a hindrance:
I can see how the latter part of the quote could be confusing:
But, note that it is not saying that the attacks start when you present the Dragonstone, but that Dragon Rising starts. This is important, because the beginning of Dragon Rising starts a series of inconvenient quest triggers that eventually lead to the end of Dragon Rising.
Bringing the Dragonstone to Dragonreach starts the conversation between Delphine and Farengar, which leads to Irileth telling Farengar that the dragon has attacked, which leads to the dragon showing up at the Western Watchtower.
I believe that the city of Whiterun is pretty useless due to panic during Dragon Rising as well, but would have to double-check that.
So, since you don't want to avoid ever entering Dragonreach, and after that you don't want to avoid the Western Watchtower for fear of triggering a dragon, it's best to just not even start the quest, lest you be forced to finish it.
As further confirmation, note that that same wiki page explicitly says:
