which, I believe, are the cells used to build the padring between IOs. As the tutorial seems to use a dummy lib (
FILL_CELLS = ['sky130_ef_io__com_bus_slice_1um', 'sky130_ef_io__com_bus_slice_5um', 'sky130_ef_io__com_bus_slice_10um', 'sky130_ef_io__com_bus_slice_20um']
) I wanted to try with the actual PDK and I found mention of padring corners with
but nothing about actual slices within the PDK. Is this to be expected ?

are all directly from the Google/SkyWater open source PDK repository. The cells you mention are efabless libraries that provide missing functionality and fill in gaps in the open source PDK. Those cells are part of the
installer (https://github.com/RTimothyEdwards/open_pdks). Use the
installer to obtain them.
