Re: What technique would you apply to neutralize Brazilian Jujitsu attacker
I think your examples assume a degree of choice that may not be present in a self defense situation.
Your strategies may work or be appropriate if you have those choices and objects available to you.
First, you must "spot the intention". You may not be able to do this. Many, i'd say most, attacks are surprises. The attacker concealed his intentions to put you at a disadvantage. He has closed the distance in someway and isolated your ability to make choices. Running, punching or choking are things that may not be immediately available to you until you re-orient and gain control of those choices again.
Good jiu jitsu systems, to include aikido, which is a jiu jitsu system, should train with this in mind. we should practice from different ranges of distance, balance, positional advantage/disadvantage to achieve a better understanding of what is available to us physically. This training should also help us understand the emotional and mental areas that are certainly triggered or effected in these situations.
To study aikido or any form of Jiu Jitsu is to better understand this environment.
