In addition to the reliability/security aspect, there's the claim to expertise and unwarranted confidence. We also don't (usually) fool ourselves into believing that the manager has gained the skills and expertise of the worker, simply because they gave abstract orders and a good result was achieved. In other words, "I can code because I prompt an LLM" is like "I can do metalworking because I sign the paychecks of a blacksmith."
