It would be nice if someone with a rule book would provide a citation, but I'd say the runner isn't responsible to disappear, but isn't allowed to deliberately change course to break up the throw either.
I think the relevant rule in ASA is 8-7-P. "When after being declared out, or after scoring, an offensive player interferes with a defensive player's opportunity to make a play on another runner.
Effect: the ball is dead. The runner closest to home plate at the time of the interference is out."
My book is a few years old so that may have been updated but I don't think so. As pointed out above, intent is not a requirement to have interference, nor is contact. (See definition of interference in ASA rule 1).
We had this sitch come up in HS ball earlier this year. R1 on first, ball hit to F6, toss to F4 covering 2B for the force, retiring R1. F4 then had to double clutch her throw to F3 at 1B b/c R1 was in her line of fire although still 10+ feet away. Blue called dead ball, ruled interference, and called BR out for the double play.
Bottom line, the runner is not required to slide, evade, etc, but she can not interfere, and if to avoid interfering she needs to do one of those things, so be it. Not doing anything except continuing on her way to 2B is OK too,
as long as, she doesn't interfere with a defensive player's opportunity to make a play on another runner.
