No, there is no such rule.
Based on the answer to the first question: If not, it is feasible to say that a pitcher could deliver the ball right-handed one pitch and then left-handed on the next?
Ambidextrous pitchers are rare but do exist. An example was Greg Harris, who pitched with the Boston Red Sox. When such pitchers pitch in the Major Leagues, they must pitch with the same hand during a batter's entire at-bat. Such pitchers may change pitching hand for the next batter, but again must continue with that arm for that batter's entire at-bat.
If there are glove stipulations, could a manufactured glove that fit either hand be worn?

This would be legal under the rules, provided such a glove meets the specifications outlined in Official Baseball Rules 1.14 and 1.15.
