Because travel restrictions don't really work against a virus like Covid.
When Trump banned China we already knew about cases in several cities, indicating there was likely already community spread. Trump would have needed to act in February at the latest, and he waited until mid-March.
New variants occuring are unlikely to be contained after they've spread to Hong Kong and Europe. A travel ban to the U.S. might be justified in this case because we don't have any detected cases yet, but still unlikely we will be able to stop them from getting in for any significant amount of time.
Is there a specific publication you're referencing when you say the WHO is critical of travel restrictions due to omicron? They likely spell out their reasoning.
Again: this is not about keeping omicron out of Europe/Hong Kong/the United States permanently, it's about buying as much time as possible.
The WHO criticized the travel bans this Sunday:

The World Health Organization on Sunday urged countries around the world not to impose flight bans on southern African nations due to concerns over the new Omicron COVID-19 variant.
WHO's regional director for Africa, Matshidiso Moeti, called on countries to follow science and international health regulations in order to avoid using travel restrictions.
"Travel restrictions may play a role in slightly reducing the spread of COVID-19 but place a heavy burden on lives and livelihoods," Moeti said in a statement. "If restrictions are implemented, they should not be unnecessarily invasive or intrusive, and should be scientifically based
They even acknowledge that travel restrictions might reduce the spread of the new variant, but speak out against it anyway.

Regarding the good old "listen to the science" argument:

Prof Rowland Kao, an epidemiologist at the University of Edinburgh who also contributes to Spi-M [a modelling group Spi-M that advises the government], [...] said travel restrictions might still bring benefits, potentially reducing the number of outbreaks and, at least for now, helping stamp them out.
And an Oxford virologist:
