it's possible to construct a set of 3 dice, such that no matter what dice your opponent picks first, the dice you pick will beat it.

2 2 1 1 1 1 1

2 2 1 1 1 1 1

2 2 1 1 1 1 1

is it possible to construct a set of 5 dice such that the total of any two dice can be beaten by the total of two other dice?

Yes! Doing the math was hard work though.

Die 1: 1 1 4 5 5 5

Die 2: 1 4 4 4 4 4

Die 3: 2 2 2 5 5 5

Die 4: 3 3 3 3 3 6

Die 5: 3 3 3 4 4 4

1,2 is beaten by 4,5.

1,3 is beaten by 2,4.

1,4 is beaten by 2,3.

1,5 is beaten by 2,3.

2,3 is beaten by 4,5.

2,4 is beaten by 1,5.

2,5 is beaten by 3,4.

3,4 is beaten by 1,5.

3,5 is beaten by 1,2.

4,5 is beaten by 1,3.
