It was ~$55 in March 2020, and most recently closed at $105. But the two key points you seem to be missing are:
1. Not all incentive packages are tied to share price. Many of them are tied to other metrics that the (shareholder elected) board decide are appropriate. This is where the bulk of Pichai’s comp comes from.
2. When they are tied to share price, they tend to be benchmarked. In this case Pichai’s share price incentives have been benchmarked against the S&P100, against which Google has been doing perfectly well. The reason for this is because directors generally don’t task CEOs with preventing economic downturns, and they typically want any incentives they create to be as effective under those conditions as they would be at any other time.
The shareholders are absolutely setting the rules for the executives here.
