First of all, I'll agree with you that Trump was much worse, and he actually started the inflation that we saw in 2021. The monthly data was showing a major ramping up of inflation when Biden was inaugurated. It just hadn't significantly affected the year-over-year data yet. Trump being worse is a different subject though.
That being said, I didn't see Biden do much to try to curb inflation, if any. I think he did try to increase taxes but, despite that failure, he increased spending. I don't think it was a great time to be pausing student debt payments and he also continued the mailing of checks (free money) that Trump started, among other things. The BIL money was a great idea, but it didn't have a funding source either.
He basically just left it to the federal reserve to bring down inflation, and then they were WAY too late.
