Is a Tiny Metallic Vietnamese Jumping spider poisonous?

Eating a spider will not poison you.

Almost all Spiders have venom. Most venoms are not very toxic to human beings. A jumping spider can have a fairly large quantity of venom that is fairly toxic to humans. However, that just means that if a big jumping spider bites you it will make you hurt enough to make you wish you had been more careful. It is pretty hard to get a jumping spider to bite you

A tiny jumping spider will be unlikely to bite you, and if it bites you then the amount of venom it delivers will not be enough to make you feel much if any pain. On top of that, a truly tiny jumping spider's fangs are so small that they might not get through the layer of dead cells on your epidermis.

Never say never because you never know what will turn up next. Probably nobody has ever been bitten by this tiny metallic jumping spider. But unless this spider is very much unlike all the jumping spiders of various species that people have been bitten by, it is a good bet that its bite would not be a medical problem for any human.
