Listen Ellers, I am sure you know, race is a big issue in the U.S. right now. Biden has stated that one of the priorities of his Administration is to address the racial inequality in America after the mess left by Trump. Everything he and Harris do, any racial implications will be taken into account. Bojo called Obama "the Kenyan" as a way of racially putting him down and making him out to be anti-British as he came from an ex-British colony when in fact he was born in Hawaii. Trump called Obama the Kenyan and Bojo followed suit. Biden will take that into account when it comes to negotiating a trade deal with the UK. Even when the UK were in the EU, Ireland still got far more American foreign direct investment. The fact that the UK is the 5th biggest economy will mean the U.S. will want a trade deal agreed, but unlike Trump, you are not a priority for Biden and he has stated that the Irish border and peace in NI comes ahead of any trade deal.
What makes you think the U.S. doesn't trust the EU? Trump was an anti-EU person who thought the sun shone out of Farage's arse. As both of them are gone now and totally irrelevant that anti-EU stance is not official American policy anymore. The fact that Biden is very much pro-EU as all recent U.S. president's have been means relations with the E.U. will return to normal.
Lastly, the EU did not crap on Ireland. An inexperienced Commission made a mistake by threatening Article 16 in the row over vaccines. Everybody acknowledges that was the wrong thing to do and procedures have been put in place to ensure it does not happen again. We are only 1% of the EU population but the fact we got the other 99% to support what we wanted means we do hold some influence and punch above our weight for such a small nation.
