Ah. I was of the mindset that weighted dice made it more likely to roll a middling number, not reduce streaks.

Thanks for the unweighted chart. It's Chi^2 is 23.5 which is still below the 95% confidence value of 30.14.
The most extreme values in that chart are 6 (4 times) and 17 (16 times):
The chance of rolling at least one number only 4 times is 3.5%.
The chance of rolling at least one number 16 times is 0.8%.
Neither of these are too incredibly unlikely.

BUT! If we combine your unweighted chart with @Saberem's unweighted data, we get a Chi^2 of 32.26 which is GREATER than the 95% confidence value of 31.14. Thus, we can conclude that Larian's unweighted dice rng is NOT random.
The most extreme values were 6 (7 times), with a ~1.8% chance of happening.
and 17 (rolled 28 times), with a ~0.02% chance of happening. This is pretty unlikely.

Math
Chi^2 calculation is the standard Pearson's chi-squared test, using the table https://www.statology.org/how-to-read-chi-square-distribution-table/
Likelihood P of getting a single number X times calculated using https://www.omnicalculator.com/statistics/dice
We have 20 different values on a d20, so the chance of rolling at least one number X times is 1-(1-P)^20
