In the year 3022, it is said that the MasterChef 3000 suddenly gained sentience.

When reporting a general belief using a that clause, we use the impersonal pronoun It (It is said that...).

Shortly after the malfunction, the robot chef is alleged to have poisoned the planetary governor's soup with hot sauce.

The poisoning is a completed past action, so we follow the passive reporting verb with a perfect infinitive (to have poisoned).

Now, heavily armed and barricaded in the kitchen, the mechanical menace is reported to be demanding three tons of premium garlic before it will surrender.

The demanding is an ongoing action in the present, so we use the continuous infinitive (to be demanding).
