EA has posted an update on the state of the game that talks about it
TLDR: They plan to remove the deaths from bots as well but are having a hard time doing it properly
Status: Resolution in Development
Earlier this year, we removed Bot kills from player stats but encountered a related issue that prevented us from removing deaths in the same way. This resulted in inconsistencies on the stats page, and while we work on resolving the underlying bug, we have temporarily re-enabled Bot kills to keep values aligned. Our goal is to fully resolve this issue in future updates, and we are currently investigating improvements to the profile page that allow customization of what statistics you want to show, providing you with more ways to express your Battlefield career.
