Trying to make sense of what would be considered dust,
Bitcoin Core have 546 satoshi as dust limit, although it was 5460 satoshi long time ago. Although the exact way to calculate dust limit is more complex, see https://github.com/bitcoin/bitcoin/blob/v28.1/src/policy/policy.cpp#L26.
Is this 0.0001 dust accumulation primarily due to negligence? Or is some other mechanism leading to so much of it? If anyone has ideas of other things to look into I'd love some suggestions 
Since you don't mention when those UTXO dust created, i would speculate most of them are created by Ordinals. See https://bitcoin.stackexchange.com/a/118262.
