Off the top of my head (not testing it):
trd() {
    if [ -r "$1/.arch-ids/=id" ]; then
        ID=$(cat "$1/.arch-ids/=id")
        rm "$1/.arch-ids/=id" &&
            rmdir "$1/.arch-ids" &&
            rmdir "$1" ||
          tla add --id "$ID" "$1"
    else
        rmdir "$1"
    fi
}

Note: This way it should be for POSIX shell (IIRC the { is required on
the same line as function name and quotes protect against
double-expansion). I have not tried it though.
