Why am I getting a zero determinant for the matrix: -2 1 1 1 -2 1 1 1 -2 if the column or row vectors don't seem linearly dependant?

Look at the webpage.
Add the first row to the 2nd and you get -1 times the third row. So indeed they are not independent equations.
... And it was. Just lack of fluency with the application of linear algebra definitions... Thank you!
