- The transaction originally funding this brainwallet split 1 BTC into neat sets of 0.001 and 0.005 BTC. Could other outputs from this transaction - there are 101 in total - also be brainwallets, or some other kind of special address? Some are still unspent, 7.5 years later.

You can see that addresses are arranged alphabetically, sorted by first two letters (first is always lowercase).
Looks like addresses were generated by vanitygen.

I thought at first you were onto something, but when you look more closely, it is not cleanly sorted. For example, the address 1Ct2qiAXf6iYHQ3iUB3sfinR5SfzhYQf4u (output 86) is alphabetically lower than the address 1FuicRGD8kQoPmnsXTirEoeoVtVwrjQs7T (output 0)

Here is the raw transaction:

And the output scripts only, which show the RIPEMD160 hex representation of the addresses:

You can see here the outputs are loosely but not perfectly sorted.

There is still something unusual about this selection of addresses, because for 92 of the 101 outputs, the first byte of the RIPEMD160 hash is between a3 and cf. This includes the address which is generated from the passphrase "just let the lovin take ahold" (first byte is b0). If the addresses were truly random, you would expect a much wider distribution over 101 values, but only 9 values fall outside of that cluster. So there's some kind of filtering going on, for whatever reason.
