Do you at least have access to a service manual? Hope the tube is ok.

These Yihua 929D-V desoldering irons are good. Saw a teardown of a cheaper one and it was pretty sketchy.

If that 2.1V cell is still holding any voltage at all, it may be chargeable up to 4.2V without significant self-discharge, but chances are its capacity has dropped, so I wouldn't expect it to last well in a balanced pack. Maybe it's only 10% lower and you'll just end up with 10% lower capacity, but I'd probably want to shove a cell balancer in there, or replace its BMS with a balancing BMS. That kind of bms mod would be cheaper than replacing all the cells, but I'd probably want to do both. Apparently even the pricy milwaukee batteries don't do cell balancing. They have the chip do balance the batteries, but it's never enabled, which is odd.

Gentle hot-air plus a cheap desoldering iron is probably the easiest way forwards, besides buying a pricier desoldering iron. I would kinda like to have a higher-power temperature controlled desoldering iron, and after some browsing I found pic related by searching for "T12a desoldering". $3 for the tip, plus another $10-$15 for a pump and foot pedal, it's pretty cheap if you're already using T12 tips like I am. Even cheaper if you just put the other end of the tube in your mouth. Though I'd need to make a 3D printed adapter from the hollow tube to a silicone hose.
I can't find anything similar that will fit into T245, TS100, or 900M tips, but with the M4 threaded tips you can buy for heat-set insert dies, you can probably make an adapter block that fits the 929D-V tips. Get it 3D printed in metal by JLCPCB for $8 or so.
