I am sorry for the naïvete if this is a simple one.

Can I please get some help on what causes the raised columnar marks on the top reverse of this off center cent?

It can't be a die issue (die break or a strike-through that damaged the die), because it is present in the non-struck off-center section.

Similarly, it seems like it might not be a retained struck-through because it appears to be embedded into the nonstruck section and that doesn't make sense. Also, there's no pattern struck into it on the minted portion, and it appears to be the same metal as the coin, which also seems to suggest it is not a retained struck-through.

Perhaps it is a planchet error, or is it something else entirely, like PMD?

I'm seeing scratches and crud on the reverse. Still a nice Off Center though.

Thank you for your help.

These are rod-shaped metal sections that are on top of the surface.

To see it, maybe focus on PLUR in the motto. The metal sections lie over and cover the letters.

In case it's helpful, try zooming in on the image in the PLUR region of the motto to see the metal covering the letters and filling the gaps between the letters.

Being out of round, it got stuck in a machine
and was poked and scratched until free.

Isn't it also plausible that if the machine was that fouled up, several prior coins might have given off all sorts of slivers and shavings as they got mangled?

Are they really raised? When I look at the E in America, it looks cut and a bit crushed by the line.

The TPGs seem to be calling these common worm shaped issues struck-through errors.

For example, here's a dime ANACs called a "Struck Through Debris" and dollar NGC called "Struck Through" (images attached).

I may be missing something, but if these are Struck Through Errors, how could they extend to the unstuck portion of this off center cent?

The slabbed coins you've posted are strike throughs. Look at the edges of the lines. They are not above the surface. Look at yours, see how the edges are above the surface of the coin. On a strike through, there would be nothing above the surface, it's not posable.

Thank you for the help. The coin is in hand. Here's some closeups of the area in the struck and unstuck regions.

The metal shards are above the surface. They do not appear to be scratches caused by PMD.

In case it's helpful, I've attached images of a Three Cent Nickel I bought recently with scratches as a reference.

That signifies a scratch. The edges are above the surface. The scrathes on the 3 cent are deeper, so they are raised ubove the surface more than your cent.
