I think I found one reason for the mistagged ways. The wiki page
https://wiki.openstreetmap.org/wiki/Tag:landuse%3Dtraffic_island
proposes to use highway=crossing + crossing=island to map a traffic island.
It says that this should be used on nodes but a mapper looking for a
replacement of a landuse tag might miss that.
It also claims to show numbers from taginfo for this combination, but in
fact it shows the numbers for
just crossing=island:
https://taginfo.openstreetmap.org/tags/?key=crossing&value=island
This tag can be used on ways, together with e.g. footway=crossing, but that
would not be used to map the area of the traffic island.
AFAIK taginfo doesn't allow to ask for tag combinations. No idea if this
occurs on other wiki pages, if so,
it is very misleading.
I think the said wiki page should be changed so that highway=crossing is not
mentioned at all.
What a mess.
landuse .. should be used for large areas.. such as landuse=residential.
Landuse=highway could be used,
that would cover the traffic island, road and footpath and the road verge.

An example of a traffic island?
Here is a 'traffic island' ... it is an overlayed way that is in the data base
see
https://www.openstreetmap.org/way/584316766#map=19/-37.60324/145.11787
I note there is no wiki guidance on tagging a traffic island in detail, such as
this island that
spatially separates entry and exit. This is not uncommon where I am.
I also note that traffic island is not part of the approval .. so this is an
addition that is not approved.
I have no solution as to how to map this in an easy way.
