New guitars are new, but not flawless. If you have the chance, I'd suggest you to change it for one that you feel comfortable with. The issues you post seem nothing unusual. Do make sure the white line is polish compound or dirt by removing with a damp cloth. If it is cracked, return it. If the nuts on the pots are an issue, you only have to adjust the height from the inside. Easy if you know how nuts and bolts work. Shouldn't take more than 5 min. If in hesitation, go with your tech.
Another problem I noticed is the selector plastic cap. My 2016 LP Traditional has the same issue where it screws too low, and the plastic touches the ring. It is a problem if you bump lightly the selector, as it will move. The solution from my tech was to unscrew it a but, but that makes it prone to falling if too much movement is performed.
If this is nothing problematic, then enjoy your new axe.
