Eliminating the lb will give a slight performance improvement, using the
lb will give you a subtle management improvement (being able to stop the
worker in jkstatus).
Different is also the way errors are handled (lb takes workers offline
after errors for a minute, direct workers will be tried for each request
even after they have thrown errors).

Is there a difference between the following 2 configurations of
workers.properties?
In the first case it is a load balanced configuration with only one
worker
The second case is not a load balanced configuration.
When there is only one worker does modJK treat it as if it is the second
case?
Are there performance advantages in the second case?
