There is only one ODELAY per IOI/IOB, therefore to use a second ODELAY you would require the use of a second IOI/IOB.
Secondly the DATAOUT of an ODELAY can ONLY be connected to OBUF (or IOBUF), it will not route to a T port of an IOBUF.
Thirdly when you are using an OSERDES followed by an IOBUFT the T port needs to be driven from the TQ of the OSERDES.
What you can do is take the DATAOUT of the Tristate ODELAY and drive an IOBUFT and then use the input side of the buffer
drive the T1 port of the OSERDES and connect the TQ port of the data IOBUFT. The obvious down side to this is the use of
the second IOB/IOI and the routing delay from IOB to the T1 port of the OSERDES.
Another option would be to use the IDELAY in the data IOB/IOI using the DATAIN port and the DELAY_src=> "DATAIN", you can
LOC the IDELAY to the same site (tools won’t automatically choose this location). You will still have the routing delays
as the output of the IDELAY goes into Fabric to get back to the OSERDES T1 port but it only uses data IOB/IOI.

#ERROR: [Place 30-574] Poor placement for routing between an IO pin and BUFG. If this sub optimal condition is acceptable
# for this design, you may use the CLOCK_DEDICATED_ROUTE constraint in the .xdc file to demote this message to a WARNING.
# However, the use of this override is highly discouraged. These examples can be used directly in the .xdc file to override
# this clock rule.

# ref_clk_i (BUFG.I) is provisionally placed by clockplacer on BUFGCTRL_X0Y31
# Resolution: Poor placement of an IO pin and a BUFG has resulted in the router using a non-dedicated path between the two.
# There are several things that could trigger this DRC, each of which can cause unpredictable clock insertion delays that
# result in poor timing. This DRC could be caused by any of the following: (a) a clock port was placed on a pin that is
# not a CCIO-pin (b)the BUFG has not been placed in the same half of the device or SLR as the CCIO-pin (c) a single ended
# clock has been placed on the N-Side of a differential pair CCIO-pin.
