When up upgrade from VIOS 3.1.x.x -> 4.1.x.x, it's not an in-place upgrade, it is a reinstall with a restoration of the VIO mapping configuration thus any additional tools, scripts etc that you have in your VIOs need to be reinstalled.
I would recommend that you install open-source software on AIX/VIO using dnf. This will make sure that all dependant software is also installed - you are missing a dependant library from your system.
I recommend that you remove sudo.rte, install dnf, then install the sudo_noldap package using dnf. Sudo has many dependencies that need to be installed along with it these days.
