At any rate, can these black holes created in colliders that exist for only nanoseconds really begin a chain reaction that would swallow the entire universe, when all the naturally formed black holes have not succeeded in doing so?

I think you might be wrong there..
All Black holes are microscopic!!!
Not really! According to general relativity, a black hole's mass is entirely compressed into a region with zero volume, which means its density and gravitational pull are infinite, and so is the curvature of space-time that it causes. These infinite values cause most physical equations, including those of general relativity, to stop working at the center of a black hole. So physicists call the zero-volume, infinitely dense region at the center of a black hole a "singularity".
The singularity in a black hole is a point, in other words it has zero length, width, and height.
But there is an important uncertainty about this description: quantum mechanics does not allow objects to have zero size—so quantum mechanics says the center of a black hole is not a singularity but just a very large mass compressed into the smallest possible volume. At present there is no well-established theory that combines quantum mechanics and general relativity; and the most promising candidate, "string theory" also does not allow objects to have zero size.
Therefore, black holes are divided into several size categories - from the
Supermassive black holes that contain millions to billions of times the mass of the sun that are believed to exist in the center of most galaxies including our own Milky Way, right down to Micro black holes.

I wouldn't worry much.
The risk is calculated at about 10 to the minus 40 - a 1 in 10,000,000,000,000,000,000,000,000,000,000,000,000,000 chance.

I feel certain of something. There is only one type of research that governments spend insane amounts of money on.

"Black hole" is a bit of a misleading term. "Singularity" would be more accurate. One particle will collide with another particle with so much momentum; the kinetic energy will force them to occupy the same space. Technically, because there is more than one particle occupying the same space, it is the same as a black hole. But unlike conventional black holes, these little ones are not made by gravitational force, but are actually created by impact.
