Can you rotate the chain tool half way into the multi tool - such that the whole tool forms an L? If so, this should give you plenty of leverage, assuming the tool doesn't break. Think of it as a folding wine bottle cork puller.

That aluminum piece, taking up most of your third picture, vaguely shaped like the number 7, is the stem. Your front fork is linked to the stem by the steerer - which you can't see because it is covered up by other parts.
