My mother has been using it because "now [she] only needs to enter her 4 digit computer pin instead of her long Bitwarden password"

Unfortunately she is unwilling to change her Windows pin to anything other than the PIN she uses everywhere else.

This has not improved her security at all. Before she switched it from what I assume was a Microsoft prompt, she had (through a bit of coaching from me) been fine with Bitwarden + TOTP
