It is not possible for me to import the package, and I get the following error message:
from numbalsoda import lsoda_sig, lsoda, dop853
FileNotFoundError: Could not find module 'C:\Users\[user]\[folder]\Gitlab\numbalsoda\numbalsoda\liblsoda.dll' (or one of its dependencies). Try using the full path with constructor syntax.

I just ran into the same issue.
When using dependencies, you see that libdop853.dll requires flang.dll and other clang related dependencies.
If I comment out the loading of dop853 to only use lsoda, then it works fine.
A couple of ideas here:
you could use gfortran with the options -static -shared (e.g. gfortran -cpp -shared -static -o libdop853.dll libdop853.f90). Running Dependencies on the dll shows 0 external dependencies besides windows libraries. The -static option takes care of statically linking libgcc, libgfortran, libquadmath...
Implementing some kind of lazy loading of the dll could also be beneficial. Like this you would not face the problem with dop853 when only using lsoda
PS: as a side note, you could add the chache option @cfunc(lsoda_sig, cache=True) in your examples for better perf.
PS2: Good job btw, I could reduce my simulation time from nearly 30 sec to 0.5!
