Is there a system wide way to change MariaDB to create tables using ROW_FORMAT = DYNAMIC
InnoDB has Limitations on row lengths and BLOBs. According to the MySQL Documentation:


  The maximum row length, except for variable-length columns (VARBINARY,
  VARCHAR, BLOB and TEXT), is slightly less than half of a database
  page. That is, the maximum row length is about 8000 bytes. LONGBLOB
  and LONGTEXT columns must be less than 4GB, and the total row length,
  including BLOB and TEXT columns, must be less than 4GB.
  
  If a row is less than half a page long, all of it is stored locally
  within the page. If it exceeds half a page, variable-length columns
  are chosen for external off-page storage until the row fits within
  half a page, as described in Section 14.3.12.2, “File Space Management”.
  
  Although InnoDB supports row sizes larger than 65,535 bytes
  internally, MySQL itself imposes a row-size limit of 65,535 for the
  combined size of all columns:

mysql&gt; CREATE TABLE t (a VARCHAR(8000), b VARCHAR(10000),
-&gt; c VARCHAR(10000), d VARCHAR(10000), e VARCHAR(10000),
-&gt; f VARCHAR(10000), g VARCHAR(10000)) ENGINE=InnoDB; ERROR 1118 (42000):
Row size too large. The maximum row size for the used table
type, not counting BLOBs, is 65535. You have to change some columns to
TEXT or BLOBs

  
  See Section E.10.4, “Limits on Table Column Count and Row Size”.


You are going to have to recreate the mysqldump so that the Storage Engine is Specified. Perhaps just drop the --compatible=mssql from the mysqldump command. The end result is the that the table will remain a MyISAM table when being imported into MariaDB.

This is just a guess but look at the error message you posted. If a BLOB prefix is 768 bytes and you have 10 BLOBs, that 7680 bytes. That leaves you with 320 bytes. If the remaining datatypes exceed 320 bytes, then it is impossible to convert to InnoDB.

Since a TEXT column is the variant of a BLOB, converting to TEXT does nothing since the storage requirements for TEXT and BLOB field are identical.
