this is easy fix
forget trace under the chip, you have nice huge via on the left, this leaves only right trace to be scraped with something sharp
in order:
-scrape solder mask from the trace on the right from the brake, 1mm is enough
-dont touch solder you already put on the pads, screwing with it might end up in another pad missing
-get yourself a hotair(even cheapest $30 858 is perfectly fine for this) and flux
-get few random pcbs from broken/discarded stuff >2000 vintage, practice lifting/soldering back smd chips on those boards, at least one hour, until you are comfy with the tool. You need to learn temperature ranges that work for you and to recognize the point solder grabs/melts
-solder your chip with hotair, kapton on both sides is a good idea
-now use a bodge wire to first solder pin over the missing pad to the scraped trace, then to the nice via on the right side
or find the nearest hackerspace, they will have good tools and usually people proficient with them
