I think the problem is calculating pi must be done in series, so you can't really get much further than anyone else. contrast that to a hypothetical situation where you could effortlessly start calculating at the nth position of pi. Then you'd have a rock-solid RNG where your real-world entropy source could repesent each digit of the index, so i.e. you get a 500 digit number, then start reciting pi from that position, now you're cooking with gas. Meaning your search space to crack the RNG would be about as difficult as cracking AES-256. but anyway I'm talking above my paygrade here, so no guarantees :)

There is this: https://en.m.wikipedia.org/wiki/Bailey%E2%80%93Borwein%E2%80%93Plouffe_formula https://en.m.wikipedia.org/wiki/Bailey%E2%80%93Borwein%E2%80... , so you can calculate later digits of pi without the earlier ones.
