I'm not sure what you mean by 'leftover' as oxygen is one of the products of photosynthesis. If photosynthesis is happening slowly, the plant cell may use all the oxygen for respiration, but in bright light when photosynthesis is rapid, the excess oxygen diffuses out into the air.
The oxygen that is produced in photosynthesis goes into the air.
When plants go through photosynthesis, they release oxygen into the air. Any plant, including greens, that go through photosynthesis produce oxygen. The oxygen that is produced, we use it.
Oxygen is produced as a by-product of photosynthesis.

The waste product for plants in photosynthesis is oxygen. During photosynthesis, plants use carbon dioxide and water to produce glucose and oxygen. The oxygen is released into the atmosphere as a byproduct of the process.

During the process of photosynthesis, oxygen is released as a byproduct when water molecules are split in the light-dependent reactions of the chloroplasts. This oxygen is then released into the atmosphere.
Any extra energy (food) which is left over is stored as starch
No, but they do make oxygen as a product of photosynthesis. Venus Flytraps work like any plant, except that they can acquire extra nutrients from bugs.

Oxygen and chlorophyll
Oxygen is the by-product of photosynthesis. Glucose and oxygen are the final products of the photosynthesis process.
