indoor=level does not add an implicit wall.

However, building and building:part probably do have outer walls by
default, regardless of indoor=level or any other indoor mapping. There's
no solution for switching these walls off yet. We can't really assume
that the absence of an indoor=wall or indoor=room element means there's
no outer wall – fully indoor-mapped buildings are the exception, not the
rule.

Therefore, my suggestion would be to include a tag like wall=no on your
indoor=level polygon for these unwalled levels.

Yes, a closed way with indoor=wall should be considered a line, not an area.

Using area=yes makes sense here, yes.

Conceptually, I'm a bit uncomfortable with wall polygons because they
break the logic for doors and windows (which are nodes on the wall
ways). But for something completely solid like a pillar, this is
probably not going to cause problems.
