These creatures mentioned in the title have characteristics (any, such as traits, costumes, behavior, etc.) attributed to anti-semitism by antisemitic people (or have their origins rooted in this)?
You don't mention any specific characteristics, specific dates or specific references so it's impossible to determine any real connexion between folkloristic iconography and some real instance(s) of antisemitism.
That said, one can speculate. From the 21st century perspective, we could say: "Well, Dwarves love gold and the Jews run the banking system, so naturally, Dwarves are a caricature of Jews." The premise falls apart once we realise that mythological Dwarves, while they do seem to be into gold and gems, come to us from prechristian times out of the far north. Unlikely, it seems to me, that pagan Norsemen would be so perturbed by Jews that they would invent a whole race for the simple purpose of denigration.
Does that mean later antisemites couldn't take those characteristics of Dwarves and turn them to evil? Of course it's possible! Tolkien fell afoul of this accusation. I think at best the answer to your query is both yes and no.
Antisemitism is almost as old as Christianity itself, and because the churches dominated every aspect of life and death, the folkloric and the religious aspects are so intertwined they are almost indistinguishable. An example of this would be the Passion Plays:
Over the course of time, Christians began to accept... that the Jewish people as a whole were responsible for killing Jesus. According to this interpretation, both the Jews present at Jesus’ death and the Jewish people collectively and for all time, have committed the sin of deicide, or God-killing. For 1900 years of Christian-Jewish history, the charge of deicide (Which was originally attributed by Melito of Sardis) has led to hatred, violence against and murder of Jews in Europe and America --Boston College Guide to Passion Plays
Another "folkloric" work that was used from the Middle Ages onward is the "Judensau" (German for "Jews' sow"), an image of Jews in obscene contact with a large sow (female pig), which in Judaism is an unclean animal, that appeared during the 13th century in Germany and some other European countries; its popularity lasted for over 600 years. In Nazi Germany, classes of German schoolchildren were sent to see the Judensau on German churches and the term remains extant as a neo-Nazi insult.
As for "costumes", the Fourth Lateran Council in 1215 was the first to proclaim the requirement for Jews to wear something that distinguished them as Jews. It could be a colored piece of cloth in the shape of a star or circle or square, a Jewish hat (already a distinctive style), or a robe.

I think the answer to your question is no. Folklore is created primarily for the ears of children and would consist of imagery relevant to the culture of the area. By culture I mean natural aspects, type of landscape, textiles created from available materials, manners of speaking and daily rituals.
First of all I don't see any close connection between the loric creatures you mention. Ogres, brownies and fairies are very different from each other.
In Norway ogres turn to stone in sunlight and come alive in the dark.
In Scotland Brownies sometimes do housework while the people are sleeping but will leave if you show any generosity to them.
In Ireland different fairies have different roles but are generally benevolent towards humans unless natural surroundings are subject to devastation in which case they may cause harm as punishment.
As far as traits attributed to race or sect is concerned I'm sure if anyone looks properly at other people they will see we are all the same really.
