What are the odds that the “tipping-bucket rain gauge” was impacted by being repeatedly shook by the storm, triggering the counters — or some other source of error, fraud, etc.?

Is there data for cyclonic rainfall that might be modeled for similar to how this article titled “How can we call something a thousand-year storm if we don’t have a thousand years of climate observations” is?

Exactly. It must be measurement error. 1.8m across the kind of area that rains falls is a "scour everything down to bedrock" level of water. It just doesn't check out. When you get that much water in one place the results make the history books.

Mount Waialeale on Kaua'i supposedly received 683 inches in 1982[0], so perhaps it's not totally inconceivable that some other tropical place received about a tenth of that in a day?

There are other records that are also ridiculous, though a lot less - check this list.
