Where can I download a precomputed openings database? With the [1600/1800/2000/2200/2500+] and [Bullet/Blitz/Rapid/Classical] and [Lichess/Masters] and [W/D/L] breakdown.

I was hoping to do some data analysis (or rather, develop an opening repertoire generating tool).

I checked https://database.lichess.org/, but the opening explorer database doesn't seem to be there. It would also be nice to have variants (especially Crazyhouse), if available.

The opening explorer database is not available for download. Its in a custom format that would require running the lila-openingexplorer server anyway (or reimplementing parts of it). At that point you might as well reindex the database from the PGNs published on https://database.lichess.org/.
