I'm just going to say it. I have had little difficulty finding all the linkedin profiles for employees in small companies (~100 employees.) Go to the linkedin page for a company and click where it says the number of employees. Click on any employee with a public profile and peruse the "People also viewed" and "People you may know" columns on the right-hand side making sure to click "show more." Keep opening new tabs, rinse and repeat.
For a larger company I once wrote a python script to do the same which helped with avoiding duplication.
If you are stuck trying to find a profile for someone and they have a picture, do a reverse image search with the company and job title and it will usually find them.
I would regard any information you put on LinkedIn as public information no matter what your privacy settings are.
I use a basically new LinkedIn account for my searches.
