Maybe the higher-ups have confused Drupal with WordPress. Drupal has very few paid modules; most of the ones I know of are related to simplifying OAuth login (sign in with Apple/Google/Facebook, etc.), which is a site-specific need.
There are some paid themes, but these are generally less than $100 and often not a "premium" experience because the default Drupal theme of Olivero is far more extensively tested and has greater browser compatibility and accessibility support than the "premium" themes. If a company really wants theming done right, they will hire someone skilled to do a custom theme.
This is true for custom modules more generally-- it would be very difficult in Drupal to do a great "paid" module because it would have to compete with a free module that does the same thing, but is more widely used and thus gets more bug reports and is better tested. However, it may be that the current modules do not support a feature they want. Some module maintainers will accept sponsorship to add features.
So, if there is money to spend, consider suggesting investing in Drupal by sponsoring the development of a module or feature that provides whatever feature the company needs that doesn't already exist. This way, everyone using Drupal can benefit in the same way that the company benefits from using Drupal.
