Good question! Yep, jb exits with non-zero:

    $ jb size:number=oops; echo $?
    json.encode_number(): not all inputs are numbers: 'oops'
    json(): Could not encode the value of argument 'size:number=oops' as a 'number' value. Read from inline value.

If you pipe the jb error into jq, jq fails to parse the JSON (because of the Cancel ctrl char) and also errors:

    $ jb size:number=oops | jq
    json.encode_number(): not all inputs are numbers: 'oops'
    json(): Could not encode the value of argument 'size:number=oops' as a 'number' value. Read from inline value.
    parse error: Invalid numeric literal at line 2, column 0

    $ declare -p PIPESTATUS
    declare -a PIPESTATUS=([0]="1" [1]="4")

So jq exits with status 4 here.
