Because of this, I didn’t bother getting level 2 charging set up at home before buying the car. Now it turns out that this particular CHAdeMO charging station is broken and hasn’t worked in the two weeks since I bought my Leaf.
Is this a blessing? Am I better off NOT using a CHAdeMO QC station?
Probably is a blessing. One of the joys of EV ownership is leaving home with a "full tank" everyday. Also makes preheating the inside of the car more efficient. If you leave at a consistent time, set a climate timer so the car is warm inside when you leave.
Will it damage my Leaf battery?
I live in the Boston area, if the weather matters.
Depends on what you mean by damage. Even at cool temperatures, the battery will have less cycles of life when quick charged. The effect isn't large. Weather does matter, loss will be faster at higher temperatures. Boston is fairly cool, 100F is rare.

The other trade-off is that the raised internal temperature created by fast charging—even though it might be below the “safe” threshold determined by the manufacturer of a particular Li-ion cell—could cause slight damage, ultimately resulting in reduced capacity and fewer recharge cycles. That said, with improvements in battery technology increasing the robustness of cells, fast-charge rates would have to be extreme to reduce the battery’s life to less than the portable product’s “useful” existence (defined as the time between the consumer buying the product and replacing it with a newer model).
Long trips in an EV are not as convenient as in a gasoline car. The LEAF more than most, due to passive cooling of the battery.
