FYI... I do not know your setup, battery location, environmental situation, etc. But there is risk with a punctured pouch due to various reasons. Be careful!
See my links. I would be worried about water ingress and electrolyte drying. Despite low levels of lithium in the battery, water ingress would be really, really bad. Instead of the electrolyte gassing off and then recombining/reabsorbed it no longer can and you have lost what ever elements of gassing from the electrolyte. Now it is drying out long term. The gasses created are all over the place due chemistry/to where the gassing is formed/which region. When packaged, the air inside the bag is humidity controlled, removing all forms of water moisture from the bag prior to sealing. This is critical to long term health. What you have is a ruptured pouch and just the exposure to humid air will certainly reduce longevity and create issues. The good news they came from LV/arid region. There is not a lot of data from people that operate in this condition as any manufacture will recommend disposal/not condone such use. Old pouches in my possession that have become "spicy" or swollen in my possession are discharged slowly, removed from my house, stored outdoors in a metal can far away from my structures and disposed of. I do this for batteries no matter their chemistry/size. With batteries of any kind, there are owners that have had fires and owners that haven't, it's that simple. I have had VRLA/AGM, NIMH, and LI either melt/required gloves to handle or start fires under normal conditions/treatment due to age/issues.
"When exposed directly to water, the lithium within lithium batteries can, unfortunately, have a dramatic and potentially dangerous chemical reaction. They combine to form combustible hydrogen and lithium hydroxide, both of which battery owners should avoid."

"Common gas species generated from typical lithium-ion battery composition are often toxic, e.g. CO, HF, SO2, NO2, NO, and HCl"

let’s see what happens!
if you have OCD do not scrutinize my temporary set up too closely. Suffice it to say that my 360 watt 48v to 12v Dc-Dc converter only supplies around 100 watts continuously. Any amount over that creates way too much voltage drop and my PC and GPUs crash. So, I took the slightly punctured battery I got for free from @Will Prowse and repurposed it to stabilize the voltage of my converter and now my DIY mining rig (1 CPU & 1 GPU) is running 24/7 off of DC
