The amount of impact they will have during those match-ups are is constantly up for debate but it is fairly safe to take a conservative estimate that you can give the pitcher credit for about 75% of those and the rest giving credit to the fielders. So pin about 625 PA on the pitcher.
An everyday player will get on average about 650 PA along with the defensive plays they make in the field they will come out creating a much higher impact on a team's success.
The pitcher has an impact on the PA of everyone that they face, I don't understand why defense would diminish their impact. You could make a case that certain pitchers would have diminshed value if the team were poor defensively. But even in that case the fielders do not diminish the pitchers performance, just the resulting outcome. Perhaps i'm getting ethereal here. But if you look at DIPS then it makes it clear that a pitchers performance can be measured fairly accurately without taking fielding into account.
DIPS says exactly what I was saying. That pitchers don't control the outcome of every match-up. The outcome of Balls in Play are usually based on a combination of the pitcher, the fielders and a level of randomness.
