1. Dick wouldn't need an archangel blade to kill Michael, he would simply mow on him to dust. But to answer your question more directly, no, Dick couldn't produce an archangel blade, or anything, out of thin air.

2. Michael could definitely assemble all the materials by apporting it all to him with a thought, so fast that, yes, it would appear like he just made the weapon out of thin air. But he couldn't just teleport in, seeing as his powers are substantially waned when in the presence of Leviathan. If he had help, he could have a chance to kill Dick with it.
