This is a management decision and will certainly be driven by management's vision for the organization.

Sure, LLMs can make a worker more efficient, so you need fewer workers to perform the current tasks. However, what do you do with that savings? Typically, managers are expected to grow their businesses. In this case, you will see the redundant workers re-trained and re-deployed to new roles in the same company. Result: More work with the same expense.

Alternatively, management might be more short-term focused and just want to hit their profit numbers for this quarter. In that case, they might eliminate those positions (assuming they have that option and unions do not stop them). Result: Same work with lower expense.

THE CONTRIBUTION OF LLM CERTAINLY CREATE MORE POSITIVE CULTURE THAT FINALLY BRINGS CHANGE IN THE MINDSET OF EMPLOYEES AT VARIOUS LEVELS TOWARDS IMPROVEMENT IN PRESENT PERFORMANCE AND ALSO FACILITATE TO REACH THE PERFORMANCE TARGETS.

In the long run, there is as high possibility that AI (not only LLM) will significantly replace Human Resources significantly.
