People I have known who go to diocesan-approved TLMs have said that the priests who offer these Masses in otherwise NO churches do regularly consecrate hosts for distribution at that TLM.
A reason might be that, to my understanding, it is normal in the NO to try to give communion with hosts consecrated at that Mass, at least on Sundays, and the hosts not distributed on Sunday are retained and used at weekday Masses. It would seem natural for diocesan priests who offer diocesan-approved TLMs to do likewise.
Additionally, a substantial segment of traditionaliists do not have doubts about NO Masses and ordination rites. Those who do have such general doubts wouldn't likely go to a diocesan TLM anyway.

I know several large Catholic families in Southern California who used to attend the diocesan-approved TLMs, sometimes taking three hour trips (one-way) to attend those TLMs because Cardinal Mahony would rotate the parishes in which the TLMs were held making it very inconvenient for the Latin Mass parishioners. In these parishes, which would only have one TLM per month, hosts were often co-mingled. In fact, the priest celebrating the TLM was told to use the NO hosts in the ciborium and not to consecrate extra hosts. Thus, those attending the TLM would rarely receive hosts consecrated at the TLM.

These families told me that their youngest children, very devout, would complain that Jesus was not in the tabernacle. These same little ones also told their parents not to argue because it upset their guardian angels whom they could see. These families then started to attend either the SSPX or the TLM with Father Melito because their children would cry otherwise.

Did you know that back in the 1980s and 1990s, St. Dominic's parish in Eagle Rock was preparing the first communion class using Oreo Cookies and apple juice? As a result, many of those students did not like to receive communion because they preferred the Oreos and apple juice, so not only were NO children growing up avoiding confession, but they also avoided communion.

I can’t speak for the diocese in Rhode Island.  In other dioceses, many Latin Mass Chapels raise money for USCB which ends up in the pockets of anti Catholic groups. They have to meet quota.  They also have to participate in ecuмenical diocesan events which include charismatic yoga meditation, talks by pro sodomite cardinal and liberal feminists who can’t boil water etc.  

Yes, no money, no TLM.
