TLDR: No.
Background
In most repositories, after a user opens a pull request for a code change, another person reviews the proposed code. The reviewer can either, Approve, Comment, or ask for additional information, prior to merging the pull request. The question is, can these comments or requests be seen in Looker?
Answer
No. All that is seen in Looker is the fact that the pull request has been approved. Comments and requests around pull requests are handled entirely in the UI of the Git provider.
