> 2) Central government bails out bad loans by selling a portion of their $3T in foreign reserves, including $1T of US government debt. Chinese creditors, investors and citizens are made whole. Foreign bond prices fall and interest rates rise, causing recession and financial crisis in the US.

That is unlikely to be the result. The US national debt is over $21T now. $1T is <5%. Dumping that much on the market at once would certainly affect interest rates, but not at a catastrophe-inducing level, and all of the normal tools used to control interest rates remain available.

By comparison, the US deficit this year is ~$0.8T, i.e. the US itself is dumping nearly that amount into the market. The Quantitative Easing program after the housing crisis was $3.5T over a few years.

It's also unlikely that they would dump the entire amount at once, because causing a sudden short-term rise in interest rates is not to their advantage (they would take a bath on bond prices). But if they divested something like $100B/year, the effect on the market would be minimized.
