Hi Anthony,
You must be referring to this message:

The PDB ID in that message contains “1”  number one not “l” letter ell.  So if you use 2o1i which is a DNA, your command will work.   It does not do anything with 2oli because that protein monomer is already the biological assembly, at least according to its page at RCSB: <https://www.rcsb.org/structure/2oli>

I hope this helps,
