lib: fix JSDoc issues

Updating ESLint and dependencies will start flagging a few additional
JSDoc issues. One or two of these are simple fixes. The ESM stuff
requires throwing explicitly in JSDoc'ed functions rather than calling
another function to throw. I think this makes the code easier to
understand--you don't need to know that a particular function that
starts with `throwsIf` *might* throw but something that starts with
`throwsAnythingElse` will always throw. Instead, it's right there in the
code. This also might make it easier to improve stack traces if that's
something we'd like to do at some point.
