This issue is summarised on page 55 of the report:
"We received representations noting that the intervention of LOTO staff in some antisemitism cases was to press for action to be taken, and that this could not amount to a disadvantage. We accept that, in some cases, the LOTO staff interference catalysed action. However, the inappropriateness of political
interference in antisemitism complaints is not necessarily about the particular
outcomes that it led to, but rather the contamination (and / or the perception of contamination) of the fairness of the process.
Jewish members are proportionately more likely than non-Jewish members to
make a complaint about antisemitism. Consequently, the practice of political
interference in antisemitism complaints, and in ‘politically sensitive’ complaints
generally, put Jewish members at a particular disadvantage compared to non-
Jewish members."
There is no clear conclusion about whether the "some" cases in with LOTO staff pressed for action to be taken, rather than against action being taken, were a majority of cases or a minority. Basically, the report makes no claim that the Labour leadership interferred in the disciplinary process in order to tolerate antisemitism and stop people being expelled for it (which is the assumed conclusion that has been allowed to stand for people who don't actually read the report, and which you seem to be reiterating here). It only makes the claim that the Labour leadership interferred in the disciplinary process FULL STOP.
There is an essential part of the puzzle that it misses: which is that the Labour party's disciplinary process is an absolute dog's breakfast that anybody with any sense of justice or accountability would laugh out of court. Everything that happens in the Labour party is subject to political interference of all sorts; there is no objectivity about anything.
In this sense, antisemitism complainants were just being treated the same as everyone else. Not that I'm justifying that of course, in either case.
