Dani Olmo transfer process is only waiting for approval from Leipzig, if the club is satisfied with the offer submitted by Barcelona, Dani Olmo move to Barcelona will be made official soon. The financial difficulties that have befallen Barcelona have limited their movement in the transfer market, Barcelona is also still waiting for offers from other clubs to sell players who are not included in Hansi Flick plans this season.
Hansi Flick is keen for Dani Olmo to join Barcelona, he is reliable up front and would be a suitable partner for Yamal. Dani Olmo background as a player from the La Masia academy means he will have no trouble adapting to Barcelona style of play, and he has already agreed to the contract offered by Barcelona, but they are still waiting for an agreement with Leipzig.
RB Leipzig could accept an offer from the Barcelona team for player Dani Olmo as long as the contents of the offer are very reasonable. Because as you said that Barcelona is experiencing problems with its own financial condition so they certainly will not make a high enough offer that could exceed their ability for a player like Dani Olmo. Although Dani Olmo is a player who has received a lot of attention in this year's Euro competition and this has made Hansi Flick interested in recruiting him to Barcelona.
