left handed relief pitchers with most strikeouts per 9 innings 2023 while pitching at least 30 innings

I didn't find anything for this season, but Aroldis Chapman had the highest K/9 by a left-handed relief pitcher with 30.0+ innings pitched in 2024, with 14.30 per nine innings.

Interpreted as:
left handed relief pitchers with most strikeouts per 9 innings 2023 while pitching at least 30 innings this regular season
